Shoulder > front deltoid

I hurt my arm my junior year took a break for a while and now im back in season. When i throw i feel like im not reaching my full power and getting the wiping action in to a 100%. During off season i worked out did bands, the works.

When i throw and i mess up on mechanics i get a pain in my front deltoid. It feels like a ligament. but im not a 100$ sure. any ideas

Sorry for the long link. but right around where the x is in the picture.

same here

Have you been to the doctor yet and had a professional physician look over your arm?

If not I suggest you do that rather then try and get help from an internet message board. The human body is so complex that it could be a wide array of speculations as to what is causing this pain.

Go get it looked by a qualified physician.
