Hello, A bit history: i am playing badminton second year, twice a week now. At the end of first year i started to feel shoulder problems. I gave it a rest for a month and half, which was a good decision since shoulder stoped hurting. Second month into the season 2 pain came back. Im assuming its rotators cuff injury. When i lift my elbow sideways i can feel the pain. Pain goes away after 3-4 days of not playing, but comes back right after training. I think this is happening because my technique is not always 100% and im using astrox 77 4u, strung at 29 Ibs, with medium flex shaft. I think my arm is not strong enough to wield this racket. So I am wondering, if i change racket to headlight version, with lower tension, will this cause less strain on my shoulder? If so, does any1 has any recommendation? I also have doctors appointment to check it out. Thank you in advance.
