I was Stung by a wasp two days ago below my right elbow and the swelling and the itch is worse. The Itch just won t quit. It also feels warm. But the weakness, throbbing/shooting pain, numb like feeling, (as if my arm is about to fall asleep), and pain when I use my arm, (like deep muscle ache, even when I use my fingers), is starting to worry me. Is this normal?
