<s>[INST] Hi I was wearing heels two day ago and fell on my knees, mostly my right knee. There is a visible bruise on my knee. The pain is not unbearable but it is bothersome and it throbs. My calf feels very tight and so does my hip. I injured the same leg a few years ago. Should I see a doctor? [/INST] Hi, you have a knee bruise and tense calf after the fall.it is possible that you have developed deep vein thrombosis of the leg. You have not mentioned if you are on any medication.Anyhow this will need a checkup and Doppler scan of the limb which will tell you exactly what's going on.Meanwhile, you will need some tests to know the clotting capacity of the blood along with a general blood profile. Regards and hope you get better soon! </s>
