<s>[INST] I fell over a year ago and the area directly after my knee remained with a now noticeable lump on each of my legs, in the exact same spot.I do not have diabetes,high blood pressure or any health issues currently. The swelling does reduce when i took water pills,prescribed after the doctor saw the swelling ,He said it was nothing and could be from veins, they are also permanently showing since I the fall..I am 30 years old. I currently lost 19 lbs but it hasnt helped. I walk every morning and use my treadmill in between . Can you kindly give me some advice as to what the problem may be. [/INST] Hi, DEar, thanks for your query to Chat Doctor. I studied your query in depth.1-In My opinion the painless lumps on both the knees -post trauma a year back, which reduces on the water-pills(Tb Las ix-?) is mostly an -MB Cyst or the Patellar Bursa-Cyst.2-I don't think it to be from the vein, for which I would advise Surgeons consultation, who would fix the cause with more detailed study.3-Hope this would solve your query.4-Wellcome for any more questions on new or this subject also... Have A Good Day.!! </s>
