A few years ago I was in a tug-o-war. I was a body builder at the time and had very developed pectoral muscles. After the tug-o-war, I noticed that it almost felt like my pecs were constantly pressing on my nerves under my arm, near my armpit, causing a shooting, burning, tingling pain down my arms. The only thing that I noticed that helped it was if I stopped lifting weights. Recently, I tried to start lifting again, which I love to do and the pain is back. The lifting seems to irritate the nerve. Is there any surgery that can fix this so I continue lifting weights?
