I cannot figure out what I did to my shoulder. About 5 weeks ago I woke up in the morning with an excruciating pain in my shoulder that affected my neck too. I was going to physical therapy already for my neck, so I told the therapist and she said I may have "hyper extended my shoulder". She worked it out and it felt better for a while, but last night I did my Christmas shopping and was carrying around a heavy package and felt a pull and now I am in the same boat with my shoulder again. When I walk it pops, and it radiates into my neck. Should I see my orthapedist? Any ideas what it could be from? I know I had to have done something to it the first time around and I thought the therapist "cured" it so I hadn't thought the heavy package I was carrying would have re-injured it.
