I started with pretty extreme weakness in my legs and pain in my back and hips. My primary ruled out orthopedic causes and referred me to a neurologist. I am now seeing a neuromuscular specialist. So far all labs are seronegative and myositis has been ruled out. My first EMG showed impaired nerve conduction. I just had the single muscle fiber yesterday. My neuro is taking my symptoms seriously and started me on low dose prednisone, mestinon and lyrica for muscle pain ( I think the pain is from changes in the way I walk, tripping, etc) The treatment has helped and has allowed me to keep working- but I still don't feel great. The fatigue is real. I'm scared that everything will be negative and it makes me feel crazy. I just want confirmation and I am tired of waiting months between tests. Has anyone had this issue?
