I don't know if this happens to anyone else here. Don't know how to explain but I'll try. Sometimes, when forehand clearing or smashing, it requires a very fast swing. That's what I do, I swing fast and sometimes I do not swing my arm in the "L" shape, it looks more like a "[". Maybe that's a bad explanation but recently, when I swing fast, my shoulders crack and it hurts. Almost feels like if I swing any faster, it could dislocate. Has this happened to anyone? Maybe my form is crippled or my shoulders aren't meant to play badminton.
You have to keep your arm in the L shape for most of the swing. Also, you shouldn't be swinging as hard as you can for clears. For smashes, why not try using 90% of your power instead of 100%. Clears should be around 50% or less of your power.
I kind of know what you're talking about dave. If possible you should stop playing for a while and ice and stretch your shoulder. If it doesn't feel great in a few days maybe you should see a doctor.. If there's nothing wrong with your shoulder in a few days get some personal help with your technique
It's just temporary pain, for a few minutes when the shoulder joint cracks. Lol. I think I better work on my stroke.
