I probably should have gotten checked out, but at least I'm okay now. I had the welts and pimples, but I didn't squeeze the pimples since I'm very cautious about infections. I am allergic to almost every antibiotic I have ever taken, so several years ago, my doctor advised me to look into herbal medicine. I did, and now I tend to go that route 99.9% of the time. I had stinging nettle on hand at the barn because I use it as a supplement for my horses (good for teeth, hooves, skin, hair, allergies, digestion, arthritis, blood, etc). I know that it's also good for insect bites and stings, so I made a paste out of it and the green tea I had brought with me as my drink. No super clean water at the barn. We have well water, but have been advised not to drink it, so I didn't want to put it on the bites. So paste of nettle and green tea went on my arm and the stinging temporarily went away so I was able to spend my usual time out there. I didn't ride because I was feeling woozy, but I removed all the hay from the stalls - using a stall fork and not my arms! - and then put down diatomaceous earth on the floors because I was worried my horses would be attacked if I didn't kill any ants in the stalls. When I got home, I felt like I did when I had a reaction to cephalosporin, so I took benadryl. I continued to feel like my body was fighting really hard with itself for a few days, but I just kept treating the wounds and resting until I finally felt better. It has been the worst year for insects out there that I have ever seen. Wasps, hornets, ants, horse flies, regular flies, ticks, etc. Really bad this year. The only thing we're not dealing with seems to be mosquitoes, and I think that's because we have bats, barn swallows, and dragonflies out there.
But, Raya, I will 100% not pick up hay off the ground without using a stall fork from now on. No more arms. Thank you for all this info because I have not had an experience like this before, so I had no idea how bad it could be.
