This started about 2 months ago in mainly my hand and fingers. It extended to my wrist, then forearm. My primary said "tennis elbow" and gave me a cortisone shot. It didn’t help and I’ve had lots of cortisone shots in my hand and wrist over the past several years. He sent me to an orthopaedic who said it didn’t seem like carpel tunnel but had me tested. The nerve conduction test and EMG testing for pinched nerves and nerve damage came back fine. Now he wants me to see a neurologist to rule out MS. No other symptoms that I can think of. The muscle weakness has now started in my upper arm. It hurts to type at work, brush my teeth and even drive. (It’s my dominant arm.) Any thoughts?
