Hi, Welcome to Health care magic forum.
As you describe, therew is a lack of
physiotherapy, mainly for knee joint, it is a must. There could be some structural abnormality at the bone ends.
I advise you to consult an orthopedic surgeon for diagnosis and treatment.
You may need to have an M.R.I. and other tests for diagnosis.
I usually prescribe to my patient with such symptoms neurotropic injections for 10 consecutive days, and then periodically,
diclofenac,
paracetamol,calcium,and
multivitamin supplements.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods till you get relief.
Wishing for a quick and complete recovery. Thank you.
