I have had very weak muscles for over 10 years. Just got a diagnose of MG about three months ago. All of my blood tests came back negative but I had the single nerve EMG and all of pointed to MG. You really should go to a neurologist that will give you a complete Neurology exam,blood tests and is knowledgeable about EMG Nerve testing. I guess my MG is called seronegative which is a rare form of MG due to tests coming back negative. I fall quite a bit but luckily just a split head on the back, broken ankle and bruises. Its quite scary. I am on 40mg of Prednisone daily which was recently increased to this dosage so I guess I have to give it sometime. I went to a Physical Therapist per the request of my Neurologist to help me strengthen my body. If a person with MG overdoes the exercise it may make the fatigue/weakness worse and need to rest the body for awhile. My PT told me just do these easy arm exercise with light weights, easy squats, core workout (also easy) and back ones. Then rest afterwards.I cannot run anymore as I will just fall. People, this disease is so frustrating isnt it? Again,please see a Neurologist.

Take care
