I am new to all of this so I am hoping to get some insight from others ..I have recently fallen and have pain progression from neck to left shoulder blade and is starting down the back of my arm and forearm to my hand. I have fibromyalgia so I do not know if this pain could be a result of all the muscle pain associated with falling or not. It doesn't necessarily feel muscular. The pain is non relenting and I am having a very hard time coping since I can find no relief. I see a pain center that deals with long term Medications and I have a spinal cord stimulator for lower back issues. I have seen a orthopedic surgeon specializing in spine who performed two of my lower back surgeries but did not receive much info if any. He verbalized that if my pain was on the right he would suggest surgery but since it was on the left he wanted to wait a month
As my MRI was not consistent with my symptoms of left sided pain. I can't barely think of making it a week longer with no relief.
My MRI showed
C4/c5..broad based disc osteophyte complex. Canal narrowed with anterior surface of cord deformed. Facet joint arthropathy. Moderate narrowing of the right neural formina.
C5/c6..broad based disc osteophyte complex. Facet joint arthropathy and ligamentum flavum hypertrophy Anterior and posterior surface of the cord is minimally deformed. Canal is mildly Narrowed. Mild narrowing of the left. Moderate narrowing of the right neural formina.
C /6-7 broad based disc osteophyte. Facet joint arthropathy. Canal is mildly narrowed. Mild narrowing of the right neural formina and moderate narrowing of the left . Any suggestions on what this means or could be causing my pain please advise.

I bolded some main points that you can search more about.

Did you fall on your left side or catch yourself with left arm/shoulder?
Any tightness in your neck, chest or shoulder?
If the drs feel the MRI does not point to a clear cause of pain & symptoms for you , then you might want to read about thoracic outlet syndrome (TOS) for short..

Your symptoms may fit into the definition of positional cord syndrome. Please see www.positionalcordcompression.com for more details - in specific the ligamentum flavum hypertrophy. pc3 pretty much says fibro is due to cord compression.

Did you have any neck trauma ie whiplash? Is your pain worse in extension? Then its very possible your issue is PC3.
