Have you changed the soap powder to liquid, that you was your clothes in ? I am fine but a pal has an allergy to Bold liquitabs but not the powder.
It could be a form of shingles, go show the GP.
Beware walk-in clinics advice, I walked in with a rash above one eye that started in the US, walk in clinic where the duty nurse said it was a mild dose of shingles, it was not contageous and as it was over 4 days old they could do nothing they could do too late to take any tablets. Went straight from there to Moorfields eye hospital A&E, where a consultant told me it was shingles & contageous and stay away from children and vulnerable people for seven days and started me immediately in the hospital on a course of anti-biotics.
I prefered to take the consultants advice.
