[|Human|] My mother had a full knee replacement in 2010. Saturday, she fell and landed on a piece of plywood. Almost immediately a goose egg popped up on her knee. After icing, the knot went down, but the knee is still swollen. Today she had some tingling in her foot, when she looked down, the blood vessels in her leg were protruding upwards toward her knee. She feels a like sluggish and has a slight headache, but doesn t think it warrants an ER run. She is currently 72, weighs about 160 lbs. She controls her blood pressure and cholesterol with medicine. Your opinion please?
[|AI|]  Hello, I have studied your case. As pre your history infection/VENOUS CONGESTION is likely diagnosis DO NOT IGNORE INFECTION IN POST TAR. You may need to investigate like CRP, CBC, ESRPCR culture is very useful to find culprit organism. If infection is confirmed then debridement is required. Persistent infection revision operation is required. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care
