Help help I was just stung three times by hornets on the arm what should I do I already applied ice and I dont?

Calm down. If you are using ice, great! elevate the extremity above the level of the heart. This will help with swelling. He you are not having difficulty with breathing (wheezing or trouble getting breath) are not feel as though you are going to pass out, not having hives or other major symptoms and not known to be allergic to stings, then relax. Take some Benadryl (diphenhydramine) and observe. Otherwise see md or 911.
