[|Human|] Hi, I am a 48yr old woman with high blood pressure controlled with lisinopril, and diabetes controlled by diet and metformin. 4days ago I got a real hard pain in the bend of the back of my right knee. A hard lump the size of an egg came with it. It felt like a Charlie horse and I could see it moving. 10mins later it stopped hurting but the lump remained. I haven t hit it on anything and I don t know what s happening. Today 4days later it s hurting really bad and every time I walk the pain is horrific. What is your opinion? Do I need to go to the E.R? My sister says it could be a blood clot. Am I in danger?
[|AI|]  Hi, greetings from Chat Doctor. Since you are having high blood pressure and diabetes it is common to develop rupture of blood vessels[as there is high chance of aneurysm of blood vessel] .in your case there would have been an injury to infrapopliteal vessel resulting in the hematoma in the back of knee. These hematoma are severely painful. And it can expand.in my opinion you have to immediately go to E. R and consult a vascular surgeon. Further delay may worsen your situation.
