I have had a rash that started 3 mos., ago, that were small blisters on my back, chest and stomach. Went to urgent care and was given steroids. Did not go away, went to er and had low potassium and gave me topical steroid cream. Still not go away, went to my dr., and thought it was a fungis rash. Got a little better by taking a vaginal yeast infection pill once a week for 4 weeks. Started to go away and won't seem to go away, Help!!!!!
