It seems each of us has our own cross to bear with the side effects and pain. Mine is so intense some days I just want to cry it debilitates me totally. I also developed a torn rotator cuff and it send out unbelievable pain shocks. Some days it feel like a knife is in my shoulder. Other days it is better. I too have been to doc after doc and never got a straight answer from any of the. The nurologist told me I should be thankful to be alive and to have a wonderful day. I am exercising and it helps a litle but it is not the only answer because I am very much uncomfortable most of the time.
