when you are seen, your provider will examine you and if need be, do more testing. If they suspect intestinal worms, there is testing they can do. if they suspect yeast but aren't sure, it's very easy to do a skin scraping ( not as painful as it sounds ) and examine the cells they scrape off under a microscope to look for yeast.
i'm going to clinic next week to have test. Could this be some kind of parasite, or what type of rash could this be? Doesn't have the yellowish filled blisters like herpes. But has tingleing sensation. Could it be yeast infection and how could I tell?
odds are this isn't herpes going on from the sounds of things but you'll need to see your provider for a proper work up.
