  • Support group for people who have Fibromyalgia
    Welcome Gigi and everyone! Anyone have any input on what makes living with Fibromyalgia more bearable?
  • Support group for people who take Lyrica
    I have gained about 35 pounds, and I have the cognitive effects listed in the prescribing information--problems with thinking and concentration." I've been off Lyrica once, and the side effects went away, but I couldn't get out of bed in the morning

Can you answer these questions (Ask a question):

  • What is the highest dose of demerol i can take at once and still be safe?
    I had major reconstructive back surgery
    With 2 titanium replaced vertebrae
    Fusion and pins holding 2 broken facet joints
    Together. I have post surgical herniation in
    Remaining vertebrae and post surgical nerve damage
    Radiating down both legs. Since Vicodin 750/750 has been taken off the market
    Nothing is helping me. My pain mgmt doctor is trying
    To help, but that means trying something new at a relatively low dose for a month then
    Reassessing. Which means I'm miserable for a month at a time if it's not working
    I'm almost out of options because nothing seems to be helping
    Years ago I had luck with Demerol injections in the hospital so I agreed to try Demerol pills now I'm stuck again with something that's not working. So my question is how many MHD of Demerol can I take at one time and still be safe. I have to survive until my next pain management appt June 4th
    And I'm in excrutiating pain. Any body know? Thank you
  • Has anyone ever had anxiety attacks while taking miralax? (1 answer)
    I have been using Miralax for at least a year,with no problem.Now,I'm having anxiety attacks & my head itches all the time & I do not have dandruff...Is there anyone who has had anything like this while using Miralax (Polyethylene). HELP!!I'M MISERABLE!!!I have to take something for constipation,but I don't know what to do,if it is the Miralax causing my problems.
  • I developed excessive saliva production after starting ropinerole (requip) for plmd. sleep was impossible due to frequent swallowing. has anyone else experienced similar symptoms? (1 answer)
    The first 5 drugs above on my list that I tried for PLMD, I no longer use. I took ropinerole (Requip) for about 2 weeks when I noticed that I was producing more saliva and was swallowing a lot. It didn't really bother me too much, because the other drugs that I take give me a dry mouth. When I went to bed, trying to get to sleep was impossible, I had to swallow every 10 – 15 seconds all night long. My doctor investigated and found that only 1% of patients develop this symptom, lucky me. I discontinued using it. The symptom went away, and then came back even after I had stopped taking the drug for over 1 month. Has anyone else experienced this over-production of saliva during and/or after discontinuing ropinerole (Requip)? And if so, how long did it last and what can be done about it? It is disturbing my sleep so much that it of itself has become a sleep disorder. Any suggestions?
  • Do you ever have a tic with speech difficulty
    I was in the hospital on life support with TTP, I was given chemo as a part of my treatment, I survived :) I previously had breast cancer with Chemo..... This has left me with chemo-fibromyalgia. I am taking 225mg Lyrica twice a day... at times i have what i have a speech tic...feels like electrical energy racing through me.

    Does anyone else experience this
  • Is there any literature on lyrica and memory loss?
    Take Lyrica for 3 years now (2010- 2013)for severe Fibromyalgia related pain. Pre-diabetic symptoms since 2012. Relief from constant pain, pain comes mostly at night now, but I am able to finally sleep. Not restful, deep rem sleep but my brain slows down and I'm not making videos in my brain all night long. No dreams now, but no dreams before either.

    Had side effects of lose teeth, but that has since stopped and teeth are again healthy again. Had ringing in ear, and blurred vision, but hat has subsided after the first year. Had legs swell at ankles and feet but that has since stopped to.

    Generally Lyrica has been good at taking the daily Fibro wide-spread body pains away but my one torment is my loss of memory. I feel as if my brain is fried! My neuro-transmittters are not transmitting. There seems to be breaks in the memories and my ability to form new memories as well as pull forth old ones. I fear that this is permanent and when I try to do brain games and puzzles my head actually hurts! I know is sounds weird but this is my experience while one Lyrica. I also have taken muscle relaxers while on Lyrica. Flexeril and another one before that, can't remember the name of it now. I have taken opiods with Lyrica in the past but now I only take 50 mg of Tramadol twice a day. I am on 200 mg of Lyrica a day. 150mg at night and one 50 mg pill in the morning. If I don't take the morning pill my brain will not work at all.

  • Severe leg/foot/ankle swelling from doxycycline
    Was given five-day course of doxycycline for sinusitis and laryngitis. By end of third day had ankle edema (never had before), then MASSIVE leg/foot/ankle edema by fourth day Discontinued on fifth day after research revealed side effect of doxycycline. Took almost a week for swelling to go comletely away. Also felt completely exhausted and seemed to make the coughing and laryngitis much worse also.
  • Blood sugar level while taking veltrex
    I been taking Veltrex for a viral infection in my eye for 3 days and today my blood sugar was 448.My normal blood sugar runs around 146.
  • Sodium phosphate sensitivity - chlortrimaton helps
    When I eat meat or any product with Sodium Phosphate in it, either in one large dose or cumulatively I get all of these symptoms. It gets worse if I eat it in consecutive meals and/or days. Taking Chlortrimaton eases the symptoms. The Doctor says this is not an allergy but is a sensitivity to Sodium Phosphate. There are other meat tenderizers and preservatives that have one or more of the symptoms listed but I have not been able to identify them.
  • Leg pain especially near knees after taking lyrica
    Had to stop taking Lyrica due to joint pain in both legs. Difficult to get up from sitting position to stand. Ache in knee's can't relax to sleep. Motrin and vicodin not helping with pain. Also have applied muscle cream not working for pain. Have been off the lyrica for 3 months with no let up in pain. Did not have this pain before taking lyrica.
  • 3 strong drugs together against neuropathic pain
    Neuropathic pain debuted when I was 24, now I'm 50. Received diagnosed with Ehler-Danlos syndrome (EDS), joint hypermobility type, when I was 35 years old. So it can take some time to get a diagnose. And as EDS-patient I do not belong to any clinic. Orthopedics says that EDS is not orthopedic, rheumatology says that EDS is not an autoimmune disease, GPs say that EDS is too difficult, and so on. Sooner or later we all end up at Psychiatry, even if we are not depressed.

    The first kind of pain I got when I was 24 came from low back, but I experienced as pelvic pain and leg pain. It was clearly a neuropathic pain, but it took years to find out. Later it was treated by a pain clinic with cortisone around the genitofemoral nerves (both sides). Since this treatment didn't result in lasting freedom from pain, the pain clinic started to give me RF (radio frequency) treatment. This made the pain disappeared after one year, and I was 80% free from it between 2002 and 2014, 12 years. The pain doctors said pain could return after 10 years.

    The other kind of neuropathic pain started 2003 with intense stomach pain. During 6 months I could hardly eat nothing due to nausea and vomiting. After this 6 months, stomach pain changed to almost unbearable pain in upper back.
    What happened 2003, and what all the doctors missed, was that the right lowest ribs slid up over the sternum. This rib dislocation is till there today, but now with a lot of cartilage formed around the rib where it is stuck in the lower end of the sternum. The dislocation is clearly visible on X-ray. This has greatly affected the thoracic spine. I have a scoliosis which I had not before 2003. And I still have severe pain in the thoracic spine.

    It was initially treated with morphine daily, and later with Durogesic (fentanyl), but this didn't help much. 2005 I was hospitalized because I had too much pain to take care of myself and my hygiene. After some months the doctors started to give me clonazepam because the muscles along the spine was in a chronic seizures. Clonazepam helped, but I could still have a lot of pain in two vertebrae in the thoracic spine. It felt as if someone drilled into the vertebrae without anesthesia. After a few months, doctors also prescribed me methadone. Then the pain disappeared almost completely. Since 2006, I have eaten clonazepam and methadone every day, and I need to sleep in an armchair to not get more pain because of moving during sleep.

    There are side effects. After 1,5 years with clonazepam and methadone I started to have panic attacks. Or rather one long panic attack which didn't stop before I got treatment with amitryptilin and pregabalin (Lyrica). These 2 medicines stopped the panic disorder completely after some hours, and the panic was then gone. Then I got side effects of these 2 medicines, amitryptilin & Lyrica, too. I gained a lot of weight (from 83 to 148 kg) and got much water (edema) in both my legs under the knees and in both feet. The feet could swallow to the double size. 2012 I stopped with amitryptilin and started to loose weight again (in Aug 2014 below 80 kg) and get less water in my legs. Today I eat as little medicines I can, but I have to take methadone, clonazepam and Lyrica every day, twice. If I try to take away one of these 3 medicines, I got pain problems at once. Lyrica is the most painful one to take away. In Sept-Dec 2013 I lowered Lyrica from 300 mg daily, to 150, then to 75 and finally 0 mg. The pain I had was extremely difficult to handle. It didn't help to take more methadone or anything else. I have checked on Internet and found that many people got pain from quitting with Lyrica. Most people start eating it again. So did I. But 2006 and 2007 it was enough to treat the pain with methadone and clonazepam, I got the Lyrica against anxiety not pain. But today I take Lyrica against pain.

    Beside weight gain and leg edema, clonazepam and Lyrica significantly affect the sexual desire. And Lyrica alone makes it almost impossible to ejaculate. All four drugs together (clonazepam, methadone, amitryptiline and Lyrica), make one forget all about sex life. You don't even miss it. When I stopped with amitryptiline and lowered Lyrica (still taking clonazepam and methadone), I could suddenly easily get erections again, feel desire, but not getting orgasms. This is quite difficult to deal with.

    The pain pattern is greatly affected, by pain and by the medicines. So is the mood. I get something which feels like heavy depression, especially if I take the medicines late that day. I should take a medicine like methadone 3 times a day, because the effects of the tablet lasts around 8 hours. But I take them every 12 hours, to have a low consumption in case doctors prescribe them too late (which happens, and then it's good to have a spouse going to the pharmacy buying them for you, because you have too much pain to go yourself).

    Since methadone is also used for treating heroine addicts, medical staff treat you with disrespect when they see that it says "methadone" in your health record. I need to show a certificate that says that I deal with chronic neuropathic pain, that I never have had problems with drug addiction, to get normal respect.

    I wanted to share this because I think I am alone in the world with these medicines in combination against neuropathic pain caused by hypermobile joints, joint dislocation and muscle spasms. After trying almost everything else, including surgery cutting nerves, methadone, clonazepam and Lyrica seems to be the only way to kill my pain. But it's a life where you always is questioned, because of the use of methadone. I can guarantee that everybody in the world should accept these medicines if they had experienced the unbearable pain I had in upper back before they started to give me clonazepam and methadone.

  • Thick uncomfortable ejaculations. Sometimes "chunks" of semen exit my penis durning bowel movements. Ejaculations look like gobs of tiny little round, very thick balls of semen making up large chunks of ejaculate...


  • From this study (8 months ago):

  • Taking xarelto after knee surgery yesterday. Foot is now swollen on that leg and would like to know if I can take the bumetanide while taking xarelto.


  • From this study (10 months ago):

  • Extremely thick, chunky like semen. Making it painful to ejaculate. Occasionally semen will come out during bowel movements in glob like increments. Ejaculations appear to be made up of small oblong jelly like balls, mixed together with semi vascular fluid.
