“Two weeks ago I woke up because of very strong pain in the left shoulder and the left upper arm. For one week I took every pain killer I had around – but nothing really helped! Then the pain got less and finally stopped. But now I cannot pick up for example my keys with thumb and index finger!”

On the pics you see his left median nerve on the upper arm – which looks like this for some centimeters. The last picture is side comparison. What is your diagnosis?
