**Maybe it was a recluse-family spider? I don’t know what those look like in general, but there are brown recluses, and some of those (3 out of 8? or so when living near Houston) are necrotic too, I got bitten when I was a small child on my chest, and apparently that didn’t necessitate hospital visits or the like. **
If it was a Brown Recluse you got bit by I’m somewhat amazed you didn’t go to the hospital. They are quite dangerous. Not usually lethal but the bite can be serious nonetheless (see below…most dangerous to children and the elderly). BTW: The easiest identifying aspect of a Brown Recluse is a violin shaped marking.
The severity of a person’s reaction to the bite depends on the amount of venom injected and individual sensitivity to it. Bite effects may be nothing at all, immediate or delayed. Some may not be aware of the bite for 2 to 8 hours, whereas others feel a stinging sensation usually followed by intense pain if there is a severe reaction. A small white blister usually rises at the bite site surrounded by a large congested and swollen area. Within 24 to 36 hours, a systemic reaction may occur with the victim characterized by restlessness, fever, chills, nausea, weakness and joint pain. The affected area enlarges, becomes inflamed and the tissue is hard to the touch. The spider’s venom contains an enzyme that destroys cell membranes in the wound area with affected tissue gradually sloughing away, exposing underlying tissues. Within 24 hours, the bite site can erupt into a “volcano lesion” (a hole in the flesh due to damaged, gangrenous tissue).
The open wound may range from the size of an adult’s thumbnail to the span of a hand. The sunken, ulcerating sore may heal slowly up to 6 to 8 weeks. Full recovery may take several months and scarring may remain. Plastic surgery and skin grafts are sometimes required.
