I've had a pain on the left side of my neck for almost two years now. At first when it would be coming, i would feel the tendon which is attaches the scapular bone to the head just behind the left ear stiffen and then sort of snap triggering an intense pain which will not allow the head to moveto the left but can allow movement to the right. This pain would radiate to the chest making breathing difficult and any movement of the arm would make the pain worse. This pain would last for upto a week and go away. currently, the pain can last up to more than 2 weeks. Although previously i would feel much pain when i made any movement, now the pain is permanently there and tthere is no posture where i can feel relief. The pain is now restricted in the neck.
I have visited doctors who think it is a muscle but i have had no response to the drugs they prescribe. Im 49 years.
