i was exercising yesterday using a slinky (the hand grip thing with springs which u pull) and i think i've injured my shoulder.
its nothing serious but when i move my arm up (like a flapping motion) i can feel the bone at the arm scraping against the shoulder. and it hurts abit also.
u all had any injuries similar to this? im hoping its just a minor (see: very very small) ligament tear and would go away by itself.
see your doctor - but don't let them just give you some medication - make sure you get treatment. I may be nothing but then again you want to take that risk?
