The conversation between human and AI assistant.
[|Human|] I was bitten by a dog 10 years ago and a hematoma (or maybe scar tissue) remained in my leg. Over time it shrunk to about the size of a penny. All of a sudden it has started bothering me and I noticed it is a little bigger, redder, tender to the touch, warm and my leg is swollen. It is on my left calf. Should I be concerned?
[|AI|]  Hello, Thank you for your contact to Chat Doctor. I understand your concern. If I am your doctor I suggest you that many a time such a scar tissue is known as Hypertrophic Scar. And should be consulted to the surgeon nearby. It requires surgical excision depending on severity of the condition. I will be happy to answer your further concerned can contact me. Chat Doctor. Infectious disease specialist. Thank you.
