Proper hygiene with frequent washing and drying of the prepuce is an essential preventive measure. Consensus-based guidelines of care are available. Circumcision may be advocated in recurrent and recalcitrant cases. consult dermatologist they will do the needful as we can't prescribe medicine online regards

Thank you for your query. You do not mention if you ate sexually active and whether your partner(s) also have symptoms. It is important to rule out sexually transmitted infections before treatment. I would recommend yousee a specialist in skin and DVD who can do the appropriate tests, see the lesions and then suggest the correct treatment. Please do not buy medicines over the counter especially steroids as these can change the appearance and make accurate diagnosis harder. hope thishelps
