So quite some time ago, when benching, doing pushups, my elbow always cracked when I reached the top position. Same with doing the tricep pushdown when I reach the bottom, everything that involves me pushing up. So I was doing the 'overhead tricep extension', and then I felt pain in a nerve in my elbow. (around 1 month+ ago) So I went to the doctor, I told him about the cracking and pain, he said you probably just injured a nerve in the elbow. He conducted a test, and he said that it's not the elbow, it's a nerve. He just said, "Rest." So I rested around 2 weeks, and I continued. The elbow continued to crack when I did benchpress etc, (no pain tho) and today it was my first day doing 'tricep specific' exercises. When doing the tricep pushdown, when I started exerting pressure to push the weight, I had a sort of sharp pain in my nerve. The cracking continued near the bottom of the exercise when I straighten out the rope. The pain is also the most severe in the nerve at that point. No pain doing everyday activities, no loss of motion. What do I do? Is it the same thing that I had before?
