Too many curve balls

Hello everyone i am 15 years old and throw low 80’s and i throw a lot of curve balls. I also think that i throw too many. However, i think this may be causing most of the pain in my arm on the inside of the elbow and upper forarm (it is a form of tendonitis i just dont know what its called but its a very long name starting with medial). Any suggestions? Are the curve balls the cause of my arm pain?

Probably, and if you’re throwing 80’s at 15 you shouldn’t need a curveball too much, just get a good change and maybe mix a curve in there from time to time.
