Hi, Welcome to Health care magic forum.
As you describe, it appears to be the pain due to
cervical spondylosis, causing pressure over the ulnar part of the bracheal nerve, or it may be due to the
arthritis.
I advise you to consult an orthopedic surgeon for diagnosis.
You may need to have MRI of the
cervical spine, and shoulder, and other tests for diagnosis.
I usually prescribe to my patient with such symptoms injections of
vitamin B1,6,and 12 for 10 consecutive days and and then periodically,
diclofenac,
paracetamol, calcium, multivitamins, and
ofloxacin.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods, to avoid the perception of pain.
Wishing for a quick and complete recovery. Thank you.
