This sounds weird, but I was stung on my wrist by a wasp four weeks ago, which hurt like a motherf****. I put aloe vera on it and it seemed to get better, however, two weeks after that, it started itching like crazy and the site started swelling again. I went to my doctor and he thought it was a localized reaction, so he prescribed prednisone and an antihistamine. A few days later, the sting site started going down and four days after, the itching stopped and I could barely see the sting. Fast forward a week later and it’s now itching like crazy - again! It’s as if I had just been stung a few days ago. The bump has come back and it hasn’t spread, but very localized, and itches like crazy. Granted, every time I weed, it seems to itch worse. I have been reading about delayed reaction and I now understand wasps leave a venom sack inside the skin and it can react with your nervous system for a bit, but for maybe a week, not a month. So, could this be TMS highjacking this stupid sting?? It seems highly unlikely that a wasp sting would still cause itching nearly a month later, right??
