Trapezius Myalgia

Last Wednesday, I woke up with what I thought to be a crick in my neck on the left hand side. I assumed this was simply due to sleeping awkwardly and so I self medicated with some non-prescription pain relief and judicious use of a heat pad. Unfortunately, the problem has persisted and in the last 24 hours it has become much worse. I awoke this morning at about 5:00 AM and as I sat up in bed, an intense pain ran up the left side of my neck and behind my ear. It took several attempts for me to get out of bed because if I turned my head in either direction or inclined my chin, the pain would again run up the side of my neck. Sitting down, getting up and raising my arms caused similar results. While dressing, I attempted to pull a t-shirt over my head. The pain in my neck on this occasion was so severe that I yelled out loud and nearly blacked out.
