Recent fall causing left neck pain with pain also in leg and shoulders. Migraine

My neck pain began with a car accident in 1990. In the accident my car went up in the air rolling 4 times before coming down on the roof of the car which then slid 280ft before stopping. My neck was crunched when the car came down on its roof. My lawyer never sent me to a doctor just one year in chiropractic therapy. Which left me every time with a migraine. After that I was having many headaches and when I turned my head for any amount of time this burning pain would begin and get more intense like someone tightening a rubber band in my neck. So I learned to turn my whole body if I needed to turn and look at something. I went for years dealing with migraines and pain with no insurance to have anyone tell me what was happening. Around 2002 I had insurance to do something and went to see spine doctor. He told me that I had several bulging discs. I did physical therapy for a year then a year of injections in the neck. When finally nothing was fixing the pain or the trouble moving my neck so this doctor went in with surgery to fix it by putting plate in my neck. I soon realized that something was wrong because the pain worsened, it was now running down my neck into my left shoulder and arm and wrapping underneath into my armpit. So I went to medical doctor to see what to do and was put into pain management. Since then I have fallen which left me having to have a reverse total left shoulder replacement. So now I have pain that medication sometimes controls to a point and sometimes not. I have like 80% muscle weakness. My doctor told me that the neck surgery left me with permanent nerve damage as well as the muscle running down the right side of my neck and continues down my back has disintegrated leaving my left neck muscle to due all the work. I now live with alot of pain in my neck shoulders and back along with so much muscle weakness. As well my left shoulder arm and leg hurts all the time. I feel as if I can’t rely on anything on my left side for the numbness and tingling and weakness. And headaches and pain in my neck all the time. I feel exhausted 24/7 and never get a full nights sleep. My family doctor tells me that my muscles in my body spazm all the time. He has me taking muscle relaxers and I can tell that they are working but not enough. I’m 56yrs old and feel 90 and just tired of living this way. I have no life because it hurts to walk stand and sit. Basically I live my life in bed and that’s not a life I want because I have grandchildren I can’t do anything with. If there’s anything else you need to know in order to compare my life to the MRI please let me know and thank you for emailing me. I thank God that I found your website… Karen
