I feel your pain. About 5 weeks ago I got bit by a yellow jacket. I had two reactions. ! about 36 hours after being stung and I realized the stinger was still in. Pulled it out and in the morning a portion of my hand was red, hot, swollen and very itchy. Took benadryl for about 5 days. Swelling went down by Wednesday. On that same Friday the hand was itchy again, so I scratched. Hand started to swell immediately. Went to ER and 400 dollars later. Eh!
2 Sundays ago, at picnic at moms. I feel a burning sensation on my calf. Don't know what the heck bit me, stung me???? Iced it, put baking soda paste on it and benadryl again. Following day red, hot, swollen and itchy. No scratching for me. Back to doctors. I have never reacted to bites like this before. It truly sucks and now I go inside when I see a biting, stinging creature.
Daughter so one of those cicada eating wasps on her deck today. First she told me it was a Giant Japanese wasp. They can kill and melt flesh. Then she realized it was not the Giant wasp but the cicada killer. I swear if it was the Giant wasp I would avoid her home until Fall.
Hope yours heals up fast.
