[|Human|] hi, i have developed since just last night a lump below my knee that is painless no matter what i do to it, and at first sight looks like it could be a bruise (red on the outside. white on inside) and sticks out more or less depending on which way i turn or the wieght i put on it. it feels like it s my bone sticking out and i have not injured myself anytime recently. please... tell me what i should do and what it could be...
[|AI|]  Hello and welcome to Chat Doctor. I have gone through your query and I can understand your concerns. If I were your treating physician I would have palpated it to look for fluctuation and skin pinch in order to rule out bakers cyst which usually doesn't cause significant problems and can be excised by surgery. I would have examined its mobility in order to rule out lipoma which is a benign mass arising from fats and can be excised if it is causing problems. I would have auscultated with stethoscope to look for any bruit which is heard in popliteal artery aneurysm. I would have done Trendelenburg test to ascertain varicose veins.I would have done X-ray to look for any bony pathology arising from bone. I would suggest you to meet an orthopedic surgeon and a general surgeon for second opinion.in the meantime remain cool and brace that area lightly. Thanks. Hope the answer is helpful. Feel free to ask further questions. Regards
