Hi, Welcome to Health care magic forum.
It appears that you have a arthritis
of the shoulder, or cervical spondylosis
with a more pressure on the nerves.
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 mypatient with such symptoms neurotropic injections for 10 consecutive days, and then periodically. Ofloxacin
sodium, and paracetamol
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods till you get relief.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to aid recovery.
Wishing for a quick and complete recovery. Thank you.
