Kathie, If it is a reaction to the antibiotic, they might have to put you on an oral steroid...sorry can't remember the name for sure...I think prednisone (?) My daughters both had an allergic reaction to an antibiotic years ago, they were covered in extremely itchy rashes, my younger daughter actually broke out in hives. Benedryl helped to some degree, along with Aveeno baths, but the steroid did clear it up fairly quickly. I hope you feel better soon. I've not experienced it myself, but I know my daughters were miserable!
