Sometimes we have a rash and don't know what it is. Are pictures the best way to find out? Unfortunately, many rashes look so similar it can be confusing. I saw 2 dermatologists who told me NOT to look at pictures on the internet. When I had a rash it looked very similar to images I saw of scabies, eczema, hives and pithyriasis rosacea. Even the dermatologists kept changing their diagnosis despite the 3 biopsies! I've learned a lot through this process.
