Sorry to hear this! Are you absolutely certain the stinger is completely out? Sometimes running a credit card or something similar over the site will "find" a tiny piece of the stinger. Other than that (since you can't ice it), it sounds like you are treating it properly. But, Lynnwood is right, if the reaction continues, or your breathing worsens, I would seek emergency care. And if you have epi-pens, I keep them close! Hope you feel better!
Take care, Fran
