I was in a collar for 3 weeks then told I didn't have to wear it, until I went back at 10 weeks, still was in a ton of pain so he told me to start wearing it again. My arm is hurting so bad again. I talked to a PT friend of mine a few minutes ago and she really thinks its a pinched nerve. I'm so scared. I can barely move it without extreme pain. I just put a call into my dr. Not sure what he'll do put I need relieve, soon.
