I'm having a lot of pain on the inside part of my elbow--right where it bends, only the pain doesn't happen when it's bent, but when it's straight and with stress on it, such as when I'm hanging at the bottom of my pull-ups. It also hurts bad when my arm is fully extended in a preacher curl. I couldn't even finish one pull-up today because of it, and I didn't even try to do the curls. I was able to do some curls seated on a flat bench with very minimal pain. The pain is seemingly coming from where the biceps attaches to the elbow joint. I'm also having some tendinitis-like pain in the outer part of that same joint. Any suggestions? I've got a doc's appointment in about a week and a half, but if any of you have any experience with this type of pain and can give me a heads up, I'd appreciate it.
