When I was roughly a year old I had a fall (don't remember how, I guess I was temporarily unsupervised but that's besides the point) and suffered a severe break to my left elbow. I don't know the full extent of the damage but I have been told it was a severe break. I was taken to the hospital, had everything put back in place and held together with screws. A few weeks later I had another fall (apparently the cast was too heavy for my young self to hold up) and shattered the healing bones along with the screws. The doctors told my mother that function of my elbow would be unaffected and the damage would just be cosmetic. Roughly two years ago (I'm 18 now) I had a surgery to release a nerve that had become trapped and was being stretched. Ever since I can remember, my left hand (which is also my dominant hand) has been much weaker than my right, has a noticeable claw-like shape to it (though I can force my fingers straight with no pain) and I cannot bring my fingers together. I can close and open it without any pain and my grip is a bit weaker than in my right hand. I play guitar (with somewhat more trouble than others) and go about my life without too much pain.
I am very into weightlifting and have been training 4 times a week for about a year now. I find exercises that involve the triceps quite painful in my left elbow and whenever I bench press heavy weight I can feel a pain in my elbow almost as if the bones in the lower half of my arm are pressing down on and trapping a nerve. I'm turning to you guys hoping that someone has a solution to my problem. My elbow does not look normal (pictures attached) and this causes me to always wear long-sleeved shirts and have general social anxiety. I'd like for it to look more (if not fully) like a normal elbow whilst still being able to continue training and lift heavy weight. Any help or input would be appreciated, thanks!
