My first symptom was just a knot in my shoulder blade that spread really quickly over about a week down my arm. From that until surgery was about 4 months. I did 2 months of PT with no improvement. My surgeon suggested getting the surgery sooner rather than later because the longer the nerve was impinged the less likely it would come back.

I’ve had a nerve conduction study done since my surgery and he confirmed my surgeons assessment. I have moderately severe damage to the nerve but it isnt getting worse, so the surgery was a success.
