I'm 21 years old and last Monday woke up with the bicep of my left shoulder sore. It was more aggravated with certain movements. It's hard to describe but I'll try my best.
-the mid area between my shoulder and elbow was slightly painful and felt pinched when I pressed down on a certain part of it.
-if I raise my arm over my head there is no discomfort
-if I reach forward or backward however there is pain in my shoulder
-the pain varies from very mild to pretty uncomfortable
-the discomfort feels deep, not superficial
I'm so confused because I haven't lifted anything heavy that I can remember. I am under extreme stress however and am suffering with anxiety and depression. I have irrational thoughts sometimes and one is that someone from my past who harassed me snuck into my room and injected me with a dirty needle. I'm scared because I'm scared that happened and that's what causing the pain, even though I have no way to prove it. I know it sounds unlikely but I can't think of any other reason as to why my bicep hurts like this. It's never happened before and my doctor just brushed it off. Please help.
