I have a swollen knee they told me I have a bursa on my knee . The swelling went down my leg and it's black and blue. The bursing accursed after I had at a Doppler done the next day .the Doppler turned out fine no clots. My leg is still black and blue. Anything I need to worry about. I'm on Kelli's 4xs a day and prednisone. I'm on my feet all day I'm wearing thigh high conpression stockings
