  • 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.
  • My experience with lyme
    My final semester at college-

    Woke up to extreme inflammation in what was determined to be a portion of my trapezius on the left side length of my next. It was accompanied by severely swollen lymph nodes throughout my entire body. I went about my day with what to me was seemingly a bad neck cramp and oncoming cold. In the afternoon I decided to participate in Track practice and what occurred after I am unsure about in terms of its relation to me performing physically or an autoimmune response against my peripheral nervous system. The next morning I woke up the left side of my trapezius was completely dysfunctional from its attachment to my cranium all the way down to the mid point of my back. It was accompanied by inflammation and sore pain at the point where the next connects to the shoulder girdle. Over the course of the next 8 months I went undiagnosed with Lyme, having seen neurologists and orthopedics in an attempt to find a solution. Reflecting on the first three months, I experienced significant effects on my emotional stability and cognitive capability. I would have severe mood swings--rage, depression, excitement-- and I would have difficulty with memory and train of thought- all of which can be confirmed by multitude of classmates. By the 8 month mark I had began to feel mild joint pain, particularly in areas I had formerly injured in athletic activity (ankles, lower back). At this point, my accessory nerve had not regenerated in terms of the portion affecting my trapezius, didn't regain any lost muscle function. I saw my physician, who discovered the Lyme infection. I took doxycycline over the next 3 months and saw significant improvement in my trapezius, which was accompanied by a decrease in lymph node size, as proven by comparison of MRIs. My fatigue dissipated and my moods/cognition returned to normal. I've regained about 70% of the function I formerly had with my trapezius (as compared to 0% prior to treatment). I wanted to write this because I have yet to see a similar case, understand the ambiguity of Lyme disease and the array of conditions it causes.
  • I switched to armour ,it's not synthetic.
    I went off after 7 years on it when I discovered a link to a higher rate of lung cancer. I switched to Armour and it handled the hypothyroidism way better.

  • I have had high blood pressure for years but it has been under control. I recently began taking plaquenil and I am wondering if this is the cause of the consistent elevated blood pressure.
