I’ve started with a red patch which suddenly appeared in my hair just behind the hairline. So itchy it was painful and kept me awake all night. Since then it’s sore rather than itchy. I thought it might be the start of shingles as it’s been so painful but no blisters have appeared. It’s not wet or oozy just red and a bit shiny but dermol cream has been soothing. So now I suspect fungal and Google tells me I need antifungal tablets and shampoo. I have a doctors appointment on Monday. Is it worth getting cream from the chemist in the meantime? Also can doctors skin scrape to check which type of fungus as I have a fungal nail and I’m worried it might have spread from there via bedding?
