I’m a 50 year old male and have been having twitching that started in my calves and now is randomly all over. I recently had an ncs and an emg. My emg came back normal but my ncs came back peroneal nerve neuropathy with no signs of entrapment. I walk with light limp because my top of foot hurts and side of knee. I’m worried about als and that’s all I can think about. Any ideas out there?
