[|Human|] hi, out of the blue i had a burning aching sensation in my right knee. the patella was red and swollen with a swollen visible blue vein across it. it was hot to touch and tender. the swelling went down after about 10 min and the redness slowly disappeared. now a larger area over the patella is blue (on the right patella top left - if you were looking at my patella). it still hurts when i bend it as well. i have had tenderness in my right knee for a while that hurts when i do squats or sit at the desk all day with bent legs. any idea what it could be as i am really worried.
[|AI|]  Hi, In my opinion hot foments with topical antihematoma with anti-inflammatory action gels will be effective for your blue discoloration and will disappear eventually it may take from 3 to 5 days. I think you may have injured both your pattern and your vein which is the reason for the swelling. For now, you may use aspirin tab twice after meals daily which will help in both your pain and your hematoma blue discoloration. If pain persists I suggest x-rays and Doppler U/S to exclude any minor fissures or fractures or any clots in your lower limb venous system.
