- My daughter has congenital php and diabetes(hyperglycemia) not diagnosed until 18.with both...now 23...blood sugars are uncontrolled nothing so far is helping
All the patients I have chatted with have LOW blood sugar but mine is high. Nothing is helping it just keeps climbing. What gives?
- I took fexofenadine for a few months last year, and had oesophagus pain and problems swallowing. i had a gastroscopy eventually. but by the time i had the procedure, i had stopped the fexofenadine.
I had started the Oesophagus problems about the time I was put on Flexofenadine. I did not at the time blame this Ryhinitis drug to the digestion problems I was having. But stopped the Flezofenadine, as it did not completely help my Ryhinitis. I was put on Loretidine for the Ryhinitis, but this made me feel washed out, so after a couple,of months I changed to Benedryl with Acrivastine . My Oesophagus problems were starting to improve. Today 9 months later, Imwent to the doctor to see if there was anything else for Ryhinitis, I have been put back on Fexofenadine, worried now that my Oesophagus will start again to cause problems.
- Does ganderma promote hot flashes
I also use the Organo gold vitamins. It seems whenever I have a beverage of Organo Gold...I get hot flashes. Is there anybody else experiencing this outcome.?
- Does anyone take oral methotrexate and use topical magnesium chloride oil. if you do, do you have any side effects?
I would like to try the Magnesium Chloride topical oil, but because of the oral MTX, I was wondering if anyone was taking/using this combination and if there were any side effects to watch for.....
- How do i change the drugs listed for me?
sleep disorders, disorientation, trouble concentrating

- Syntroid and pruritus
I have been on levothyroxine for more than ten years and have had two episodes, each lasting over several months of unbearable itching. Doctors seem to deny any connection but are also unable identify the cause of the itching. None of the tests pick anything. Antihistamines are not much of a help. I am still in the throes of the second episode and life is plain, simple miserable.
- Thrush while on prograf
I am a health provider at an emergency room and had a patient come in because of a food bolus and when i examined his oral/pharynx I noticed he had thrush. Patient stated it has been their for a while. Patient also stated he has been having progressive difficulty in swallowing. Pt is a kidney transplant patient and has been worked up for other causes of his thrush (including HIV, as per patient results neg) and everything came back negative. I can only conclude that maybe the prograf which is a immunosupressent can possible be the cause
- Cardio version caused fingernail abnormalities
Right hip fracture. When prepping for surgery AFIB was found. Surgery was cancelled and they attempted to get AFIB under control. Finally, cardioversion was performed. When my nails started to grow out they all had two horizontal lines that cause the nail to break when it grows out to that point.
- Synthroid and breast enlargement
I have went from a B-C cup size to a D cup in the past 8-9 months.
- Double vision on levothyroxine
Diagnosed with under active thyroid in January 2011. Noticed onset of double vision in January 2014. Blurred vision and double vision worsened to such an extent that my glasses prescription has changed three times in less than 7 months. All the symptons I experience are a direct result of taking Levothyrixine and have increased as my dose has been increased.
