Given that your rash has not dissipated, and you are still having some occasional dizziness, I'd get yourself scheduled with your primary care physician, or one of his associates (PA or NP). Many times it's just a matter of starting new detergent or fabric softener sheets or foods, that create rashes, but being that you also have had some dizziness, I highly doubt it's because of a new product. Rashes also can be caused by failing to rinse properly after a shower, or even conditioner that can stay on your body in areas that are hard to reach, and given that it doesn't itch you, chances are that it's not from dry skin. I'm sure your physician can provide you with information on it, and perhaps order some lab work to see if anything is out of whack. Good luck to you!
it could be an alergic reaction to something possibly new medication go to gp as he will tell you what to take or not
