Hi , I Recently Went To The Health Clinic And

Hi , I recently went to the health clinic and was given treatment for gonorrhea and chlamydia, a week later I developed small rash like bumps on head and a piece of white patchy type skin developed wondering what it can be and how to rid my self of it. Im 25 uncircumcised, and have had pearly penis since a child and this is different. Ps, will salt water help?
