For about a week now I have been having pain in my left shoulder. First it started off to be sharp pain that would shoot up into my neck/ear, then it would go back to my shoulder and the back of my shoulder towards my back. It no longer is sharp pain but it's ache pain like I just worked my muscle out. I had an episode where my trap muscle by my shoulder felt like it was burning. Then my whole arm felt like it was burning along with the upper part of my back. I have been to the hospital because pain in the left shoulder is a heart attack symptom and they did an EKG on me, enzyme blood test and x Rays. Everything came back fine and showed no sign of cardiac related symptoms. I still get scared though, this pain has been here for about a week. I'm 19 and a female.
