Hi
Welcome to the MedHelp forum!
If you are not able to lift weight then you have either a muscle or nerve injury. It is unlikely that you have injured your shoulder joint or the rotator cuff therein as this will cause pain. You need to consult a sports injury specialist to find out the exact cause for the weakness. Please avoid exercising meanwhile.
Hope this helps. Do let me know if there is any thing else and keep me posted. Take care!
it sounds like a strained or pulled muscel, the time out is good, but if weakness persists for too long, more than a week with no improvement, see a doctor, it could be serious, or nothing. if you don't have insurance, go to a local clinic, they will work with you more on price and payments.
Good luck
that is probably what it is a strain in your shoulder,doing weights have prob made your shoulder weak,go to your docs he might prescribe you anti inflammorty tablets to ease the pain
