Hi,
You could be having a spinal nerve compression in the neck or cervical region along with ulnar nerve compression in the arm and hand. This may be leading to the pain in neck, shoulder, arm and hands along with numbness and tingling. Wrong posture, spinal stenosis, spinal disc protrusion etc, may be the cause. Please go for MRI of the neck and spine, and arm and consult a neurologist for diagnosis and treatment. Please stop strenous physical work and go for gentle exercises daily. Hope this helps you. Take care and regards!
Sounds like you also have nerve compromise at the cervical level. A little bit of spinal stenosis. There is an unlikely chance you have degenerative arthritis, but most likely it's just nerve compression. You need a few days of rest. That's for sure. These injuries are peculiar, in that they often respond to exercise through the limits of pain, which is counter-intuitive. And "range of motion" exercises with the head. If you keep "self-splinting" you eventually end up with a frozen shoulder. The bad news bears. You will find that most physicians won't know how to treat this. Moderate home axial traction is recommended, for ten minutes six to a dozen times a day, two hours between treatments. A cervical collar is NOT recommended as it will decrease muscle tone. Plan stupid. Good hydration and ibuprufin to reduce infloammation. An MRI is suggested. Not a CT. Don't waste time on an x-ray. If your chiropracter suggests an x-ray run from the office.
