About 2 weeks ago or so (maybe more), I noticed a small lump (maybe 1/4 inch raised, 1/2-1 inch wide) form on my arm. After noticing it, I also began to notice that the skin on the top and around the area seemed to being turning a shade of brown and dying. However I have been moving and I did not really think anything about it until this week I realized it had been several weeks and had not gone away.
The skin on the area has died and peeled away and died again, and repeated the process a few more times. There does appear to be a red / black dot or hole in the center. It looks very similar to the pictures I have seen of brown recluse spider bites, but much smaller. Most people seem to have areas that are several inches wide where as this is an inch wide at most.
At this point I have gone several weeks so I am fairly certain any danger, if it was a spider bite, is gone. I am just trying to figure out if this will go away or if it could be something else.... I know the answer I will probably get is "go see a doctor" and I will if it does not go away but I wanted to see if anyone had any other ideas or knew if it would go away on it's own if I am correct.
