Hi, Welcome to Health care magic forum.
As you describe, you had surgeries on both hips, and a knee, years ago, that would have caused the pressure symptoms on the nerves passing in the way.
You still continuing with the pains of the nerves, in spite of the surgery on the spine.
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 injections of
vitamin B1,6,and 12 for10 consecutive days, and then periodically.
protein supplements, calcium, multivitamins,
diclofenac, and
paracetamol.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods.
Wishing for a quick and complete recovery. Thank you.
