Hi, Welcome to Health care magic forum.
As you describe, he must be having some skin infection
, Which probably spread to you. The other causes may be the urinary tract infection
, or chlamydia.It also may be the metabolic disease like diabetes.
I advise you to consult a dermatologist
for diagnosis and treatment.
I usually prescribe to my patient for both the partners,ofloxacin, ornidazole
, and ketokonazole soap.
Wishing for a quick and complete recovery. Thank you.
