Help! I’ve been in pain all week, and I’m only 16. It started last friday, right undernear my shoulder blades I felt jarring pain. I wrote it off as me being sore. This morning though, I felt that it made it’s way hp torwards the base of my neck, and I’ve been having a horrible headache on the left side of my head around my ear. I cannot move without my head feeling like its rattling. Just now though, I developed a sharp pain on my underarm, on my right side. It feels as if someone has made a slit from my armpit to my elbow and the pain is UNBAREABLE. When I touch my arm though, it burns as if I am touching an open cur -even though nothing is there. Meanwhile I have my head and back pain, I had even taken 2 tylonols this morning to subdue the headaches but it didn’t help at all. All of this pain is quite unusual, I’ve been working out and eating healthy and I just don’t understand.
