I have pityriasis rosea. can i bathe? and should i avoid certain foods like egg and meat?

No lifestyle changes: You can do anything you want, and if you've got somebody special, that's fine too. Anyone who tells you about food choices making a difference is misinformed or worse. Getting a sunburn and/or taking a little erythromycin have been said to make the illness itch less or go away faster -- your physician can be your guide. Hope you're well soon.
