<s>[INST] This past wednesday, after being home for an hour or two, I noticed that I had scraped the skin off a small area on the inside of my left ankle. There is a hard lump underneath the spot, and it is very sore all around the area, sore to walk also. Now the skin has very little coloring to it, but the soreness is continuing. Thinking it is a bruise from banging the ankle with my other foot. [/INST] Hi! Thanks for sharing your recent health problem with Chat Doctor! After going through your description, as I feel or if I were your physician, I would like to consider nothing but an infective pathology in this case! Regarding the scrapping, skin ulcer, soreness, hardness, color and painful movements, I must think that there is some recent infection only with soft tissue involvement and in worse case ti could be some kind of arthritis or inclusion cysts also! Therefore, you must see a physician for a clinical examination, Chat Doctor.  </s>
