Hi Broken Throat,
It sounds like an allergic reaction to me. By now I expect you've stopped the medication and called your doctor, but if not, please do. It's very possible that there is another option that you won't have a sensitivity to. It's not a problem I've had, but sounds suspiciously like allergy--and I've had lots of experience with that.
Have you tried any new lotions or soaps? I had a time when I was applying a lot of Aveeno lotion (I was in the hospital and had lots of time on my hands). I started getting itching and rash, and thought it might be a medication. Lo and behold, I began to realized that the itching started after applying Aveeno. So it's worth thinking about any other things you might be using that could have been fine at first, but you many have developed a sensitivity to.
