I've had this itchy rash for a few days, it's now turning tender and sore (might be from me scratching).
Google has suggested a number of possibilities including flea bites (no pets) scabies, various pox, and troublingly eruptive xanthamatosis which can be a sign of diabetes apparently.
They're not insect bites, I've had flea bites and they're not that, I've been putting bite relief cream which hasn't relieved anything and hydrocortisone which helped The itching when it was really bad.
Give me your suggestions...I will be trying to get a GP appointment tomorrow though!
