<s>[INST] Hi, may I answer your health queries right now ? Please type your query here...                                         Hi, I have a pea sized knot on the front of my knee to the left of my knee cap. It doesn t hurt unless I push on it, kneel, or exercise. It causes a deep burning sensation for about 30 minutes that is immediately strong and then lessens. I had an orthopedist examine it, but he didn t know what it was or how to remove it other than just opening up my knee. I have had it for about 4 years and it is increasingly getting larger, and is just now getting visible to others. What can it be? Thanks [/INST] Hi,Dear,Welcome with your query to HCM.Studied your query in full depth of its details.Reviewed it in context of your health concerns.Based On the facts, You mostly seem to suffer from-Synovial thickening of the Left Knee.The fact that it causes burning pain- confirms it to be from Synovitis with arthritis.Treatment-Confirm the diagnosis from Second opinion by Ortho-pedic Surgeon / or by X-ray Knee/ or by CT knee study.Arthroscopic Excision of the  Synovial Granulation thickening would give relief.Conservative care by-quadri knee-exercises / NSAID/ VitD3 -calcium supplements would help the recurence to be checked for long timeThis reply would reduce your scare, hope so.This reply would help you to plan further treatment soon with your treating doctors.Best of Luck and early recovery.Welcome any further query in this regard,which would be replied in next session.Good Day!!Dr.Savaskar M.N.Senior Surgical SpecialistM.S.Genl-CVTS </s>
