why does my shoulder hurt every time i throw something?

You may have damaged the rotor (the cuff or cup, the ball the long bone end sits in and rotates in) it may be chipped, even a small particle broken off. I would suggest you see a doctor. This may be the start of arthritis, from the injury, this is how it starts.

The doctor may want to have MRI's or a CAT's scan, then at most even minor day surgery if that's the most they'd do.

It could be, again, just the injury set in motion the hurting of the arthritis and the cuff needs to be scraped. This is nothing more then cleaning off the calcium from the cuff so it can operate smoothly again. I've had this done.

Be very careful about that your shoulder joint may be out of alignment. A year ago I had almost the same problem with the shoulder pain and throwing a ball. And my shoulder eventually dislocated, I had to be rushed to a doctor to have it put back in place, it was very painful. So I suggest that you go to a sport medicine doctor to have it looked at as soon as possible.

It sounds like you've torn the rotator cuff. This is an injury that will take physical therapy and might not ever be right. You blew your chance to get into the Major League, dude. Get some therapy, you're still growing? They might be able to do some good.

You need to get yourself down to the doctors so that they can have a look at that before you do any permanent damage. Its sounds like a very bad sprain, but go to the doctors so that they can tell you exactly what you've done

Hey

Maybe it could be caused by stressing the muscles on the joint area. Rest your shoulders and if it's getting worse or it just remains in that state, please go to a physician
