Well, I’m not sure, really. It looks bad, though, and is burning and itchy. It looks like it may be spreading a bit. I was in the Garden shed behind my house on Saturday and that’s when it happened, I think. I don’t even remember getting bit by anything that day. I never felt any discomfort until I was showering later that night and then felt the burn. I looked closer and I thought it was just a mosquito bite but it got worse the next day and it’s still giving me a lot of trouble. It could have been anything, I guess, but Brown Recluse came to mind. Whatever it was got me good!What makes you think it was a brown recluse? I was bitten by one decades ago. I have a scar on my calf, near my ankle.
