After a lot of specialist visits and tests, my official diagnosis is Cubital tunnel in both elbows. Cubital tunnel is very similar to carpal tunnel which is in your wrists, except its a nerve pinch in your elbow. Tomorrow I'm going in for surgery on my left arm, which is worse. They're gonna shave off a bit of bone in my elbow to free up room for the nerve.

Surgery on my right arm is scheduled for August 15th.

Scary stuff, but lets hope it works!
