What could this really itchy disappearing rash be, if it's not poison ivy? I only get it in the evenings?

Question

These past few days I get really itchy rashes all over my legs and feet. They look kind of like I spilled something irritating on them in random places, but I definitely didn't. The weird thing is, they only turn up in the evening, and then by morning they're gone. I've been taking Tylenol cold and sinus for the past few weeks, probably for longer than I should be. Could this be causing it? I stop taking it in the evening, that's why I'm wondering. I take an antibiotic every day, too, I don't know if that has anything to do with it.

Answer 1

It could be an allergic reaction to the medicine or to all the medicines you are taking. Id advise to talk to your doctor.  I had a rash on my legs and hips and i went to the dr and they said it was an allergic reaction and i got some pills to take and never have gotten it back.  I was never tested for allergies and the dr said it could be a number of different things and could not really pin point what i had a reaction to.  

Answer 2

Google image search "hives" and see if that's it.

If it is google the term and you'll find lots of info about them.

Answer 3

keep a food diary, use Benedryl as directed for a few days, drink more water, and see your doctor.
