Hi,Welcome to Health care magic forum.
As you describe it appears to be the
cervical spondylosis causing
nerve compression and pain of the neck, back, and arm.
I advise you to consult an orthopedic surgeon for diagnosis and treatment. You may need to have a C.T. scan for diagnosis.
I usually prescribe to my patient with such symptoms neurotropic injections for 10 consecutive days, and then periodically along with pain medication.
You can use pain medication along with the amytryptiline.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods till the pains are completely controlled.
Wishing for a quick and complete recovery. Thank you.
