<s>[INST] Hi. I had an injury to my right shin over 15 years ago. I hit a fire hydrant as I was riding my bike which caused my chin to get caught in between the two. My chin was facing outwards and the fire hydrant smashed my shin which caused in to push my skin in, as a result I had a slight indentation and severe swollen. Over the years I was told I had nerve damage due to the accident, and I always had a very slight indentation. A few days ago I noticed my shin was very sore. It has been sore for a while but it went away and never thought twice about it. Just recently I go to rub it because it was sore, and I realized I have a massive indentation in my leg. It is very noticeable especially when you feel it. I am confused because it was many years ago and now it is taking affect. Thank you [/INST] Hi you had a minor accident injuring your right shin about 15 yrs ago, and you feel indentation on your shin which is increasing now. At that time you were told that you have nerve damage. In my clinic practice, for this kind of unilateral swelling with previous history of injury, I will investigate on the lines of Deep Vein Thrombosis, by getting a color Doppler as a first step. Also, I would give you compression stockings, anti-inflammatory painkillers and limb elevation for a few days. </s>
