I have been having muscle spasms many times a day If I walk more than 10 minutes at any given time. I have been going to a local chiropractor, it has been helping for about 6 weeks. He says my posture is the problem. I only get sharp pains on my left side of the neck and behind my ear. The right side is fine, no pain. The pain is so bad it's hard to do anything: walking ,driving, sitting. I started driving a different car so I can always sit up straight while driving. I have had many MRI’s and CAT scans. I have also seen different doctors who all say the same thing "nothing wrong". I have been doing neck stretches by slowly lowering my right ear to my shoulder and holding it. This seems to help some. Any advice, or suggestions? Will the pain eventually go away? If so, in what time lapse?
