Hi, Welcome to Health care magic forum.
It appears to be the arthritis
of the hip joint, or sacroiliac joint
. You may need to have a M.R.I. for diagnosis and treatment. So i advise you to consult a orthopedic surgeon for diagnosis and treatment.
Avoid taking potato, other tubers, tomato, egg, chicken and sea foods.
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.
