Cause of Arm Pain From Pitching/Tennis?

I am a sophomore in high school and have been pitching for several years. Recently, I have been throwing an increasing number of curve balls, and have been playing on the varsity tennis team, which practices every day.
When I pitch (especially on curve balls), serve, or hit a forehand, my arm experiences pain on the outside of the arm in between the elbow and shoulder. I ice it and it feels better, but when I pitch,serve, or hit a forehand the next day, it hurts again. Also, my left arm (I’m a lefty pitcher and tennis) feels much weaker when I try to hold things out in front of me. For example, if i take a full gatorade bottle and extend my right arm out, I have no problem keeping it out there for ever. With my left arm, it shakes when I try to hold the bottle out there, and I can’t hold it straight out for long.
I asked the school trainer and she said it was a bicep injury just from over use, or a muscle strain. Is that what it is or could it be something else? Also, what can I do to make the pain go away, or heal the injury?

    i pitched for many years and had this same arm pain. i was told it was tendonitis. throwing a baseball and swinging a tennis racket are not normal arm motions. they put a tremendous amount of stress on the elbow and the shoulder. i would ice and take ibprofen to make it through the seasons. you should probably take a break then ease back into it. if you continue you are risking a major surgery, probably tommy john, and those arent fun.

    give your arm a rest for like 2 days then try to pitch again

    When I get bruised on the arm, leg or get hit on the head, I rub the wound with medicated oil. It has a very intense smell, but it works.

    Stop throwing curve balls. Any pitch that hurts your arm should not be thrown. You can risk seriously hurting yourself.
