I badly need some help people.I'm only 17 years old, and I play once a week at the minimum.My elbow and back have been recently hurting when I serve, and not on my groundstrokes. But today I just hit around and all of a sudden my arm started hurting.I have been playing ever since I was 12, and I try to ask my dad for help but he never takes anything seriously, and he ticts me off. I have took IBProfin an hour before I play, and that sometimes helps. What should I do?!?!This means so much to me guys... And I'm not sure if it's tennis elbow for sure..
