I have a rash on the corona of my penis and the head. i've been treating as a yeast infection i was just wondering what arevthe signs of the treatment working?

Rash goes away.: If the medicine works, the rash will go away, usually within 10 days. If you have not seen any improvement after three to five days, get seen by a doctor to be sure you do have a fungal infection. There are other causes of rashes besides yeast. If you have had unprotected sex, get checked for std's. Also, avoid scented products and harsh soaps/detergents/fabric softeners. Don't over-scrub.
