It has been 4 years that I have been searching for an answer for what is wrong with me. I have all over body pain, all joints hurt, I have lower back pain that radiates down my legs at times. I have arm pain that is constant in both arms. I have rapid weakness in both arms and hands. My physical therapist found that within seconds my grip strength reduced by 20% when she was checking my grip strength. Previously I tested positive for Myasthenia Gravis. I was tested again and the test was negative. I go to the VA and the neurologist was fine with a negative test and I have not seen him in over a year. I was found to be totally disabled at my social security disability hearing at the age of 33. So now I have Medicare and will be going to see my original Neurologist who found problems with my reflexes over four years ago. To me the sudden loss of strength should be indicative of some sort of problem. As well as the positive blood test for Myasthenia Gravis. I think it has to be in the family of MG. My physical therapist said that I need to find a Neuro-muscular specialist. Has anyone else experienced anything like this or know of someone who has. BTW the reason the neurologist had the blood work retested was because he said I didn't have a droopy eye like most do that have this. The test came back the second time on the high side but within limit so he said I didn't have it. Made zero sense to me. I hope when I see my Neurologist again for the first time in four years he will be able to point me in the right direction.
