Whilst on my daughters hen do 3 weeks ago we visited a spa and I used the jacuzzi. The next day I had a rash on my stomach which was itchy. After trying dry skin creams and with the rash now affecting my neck and chest i gave up and went to gp. Apparently I have foliculitis from a bacteria in the jacuzzi which doesn't normally bother people too much but because I was on prednisolone my body couldnt fight back. Even really well maintained pools, hot tubs and jacuzzis can carry bacteria.
Unfortunately the cream I was given didn't work and one course of antibiotics has not resolved this rash which has now spread virtually everywhere except my face and is incredibly itchy.
I would never have gone in the jacuzzi if I had known there was even the slightest chance of me catching something. Bear this in mind if you intend to use a jacuzzi or hot tub whilst on pred.
