So I've been sleeping on my shoulders a lot and when I umpire standing up at junior tournaments, I feel tightness in my shoulders/traps area. I went to see a chiropractor at US Open who helped loosen my traps a bit but I felt it get tight again. Now I have lost all my form in badminton. I can not clear or smash anymore. I have just started using a tennis ball to massage the muscle a bit. Is there anything else I can do at home to stretch or massage the area? Thanks for any and all help.
