I developed bad hives three days ago I think as a reaction to an antibiotic. I stopped taking the antibiotic, have been taking benadryl regularly, and was given a steroid shot yesterday. Hives still haven t gone away. I didn t have any on my face until a few minutes ago. But when I washed my face, my entire chin swelled up in less than a minute and feels numb. I m not having rouble breathing, but its still kind of freaking me out. Do I need to worry about it suddenly spreading to my tongue or throat?
