[|Human|] My husband has a red swollen knot  on his calf. His legs swell up when he wears socks and the knot started out weeks ago as a lump but flesh colored.Then it started getting bigger and started turning red.It is now about three inches across and is red with a darker color in the center and the skin is starting to peel back on it and it hurts to touch.

In my opinion, a 3-inch lump on the calf of your husband-is -boil which has grown into abscess. Treatment-I would advise you to URGENTLY consult an ER-Surgeon, who would Chat Doctor. This is the remedy for your lump. Hope with this you would be relieved of your worrisome query. Wellcome again to Chat Doctor. Have a good Day.
