Good point here. For over sixty years I have been stung and I do not have a pattern. I do not react according to the text books. Sometimes I react locally with swelling and intense itch whereas other times there is no reaction. I took six stings, same time, same hive and 5 stings were unremarkable while one sting on my ankle was massive swelling and very painful? I think the stinger hit the bone in the ankle but cannot be sure. Go figure? DYNAMIC reaction to stings is my best definition as stated by Hops and Member in more detail.
Hands feet and face are reactor areas for most folks. Generally speaking the more stings the less the reaction as one becomes immune according to the books on immunology. Shortness of breath, difficulty in breathing is major cause for concern, not so much pain, redness nor swelling: generally speaking not absolute.
I do have prednisone, RX, if I have a reaction.
