I have the same problem with getting stung. Heck, I swell when I get bit by a skeeter, and they are the official “bird” of this area!!!!
Same problem here. Now I know at the first itchy feeling head into the house and take an antihistimine (don’t buy Benedryl...to expensive), within 45 minutes the itch is gone and I won’t have the swelling and itching for 2 weeks like I used to.
Try it you’ll like it.
