Hi, Welcome to Health care magic forum.
It may be due to the post operative state, or by its own. There could be compression of the motor nerves on the front of the groin.
I advise you to consult an orthopedic surgeon for diagnosis and treatment. You may need to have an M.R.I. for confirmation.
I usually prescribe to my patient with such symptoms neurotropic injections for 10 consecutive days, and then periodically.
Ofloxacin mefenamic acid, and
paracetamol for ten days when ever there is more pain.
Avoid taking potato, other tubers, tomato, egg, chicken, and sea foods till you get complete relief.
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
