So I use to be able to hit a good consistent 1hbh; however, i took a little break and ever since my backhand has gone down. Now I hit the net a lot, and when I try to put on some power I sometimes hurt my shoulder. Feels like i'm hyper extending or popping it out of socket. I really need to get this fixed before I seriously hurt my self. I'm pretty sure i'm putting the power down wrong, but I don't really know what to fix. I think i'm hitting too high up. Please & thank you for any useful advice.
