I have suffered with the same symptoms for the past 13 years and despite seeing doctors, consultants from every department, no-one knows what is wrong with me. I even paid privately for a cervical discectomy as I had two slipped discs. The pain has not eased. Along with all the pain I have severe dizziness and balance problems. No-one can tell me what is causing this either but according to information on the internet (Round Earth Publishing) The sternocleido mastoid muscle can cause these symptoms.
Just recently I discovered a knot which feels just like a piece of grisle at the top of my shoulder. This is where all the pain is and when I press on it the pain goes straight up my neck and into my head. Also when all this began 13 years ago I carried a heavy bag on my right shoulder. Again this is exactly where the pain is.
I have had every treatment possible but no-one has ever mentioned that it could be a knot
Any comments or ideas would be greatly appreciated.
