SC, I took two "meanies" on Tuesday, one on the side of my first finger and one on the lower arm, just above the wrist. These stings have itched! (I'm a beginner, so I had only three stings under my belt before these two; I hardly reacted to the earlier stings)
I tried baking soda paste, meat tenderizer paste, taping a penny over them, taking Benadryl and ibuprofin, not much help from any of it! Ice helped, until I would take the cold pack off.
I finally resorted to soaking my hand/arm in an Epsom salt solution. That definitely helped reduce the inflammation for me.
