Hi welcome to Health care magic forum. Knee is a very complicated joint with several attachments and several varied movements. But still mysterius is no findings in MRI
. I think you better consult a rheumatologist
to look into the knee.
Besides i advise you to follow some diet recommendations as avoid taking potato, other tubers, tomato, coconut, cauliflower, egg, chicken, fish, other sea foods.
Take more of green leafy vegetables, pulses, sprouts , milk, meat, fruits, juices, and dryfruits to improve blood, general health, resistance to infections and stamina to deal with such pains.Wishing for a quick recovery and thanks for calling.
