Hi.
Noted the history well and understood the concerns.
The condition is called
Balanitis.
Balanoposthitis if the prepucial skin is also similarly affected.
I would advise you the following in such a condition:
Clean the area with plain water 2 to 4 times a day and and keep it dry with a pure cotton cloth or a dryer.
Apply liquid
Povidone Iodine locally or a
Metronidazole cream.
A course of antibiotic and metronidazole orally for 5 to 7 days and a single dose of oral anti-fungal tablet should help you to get a cure if local hygiene fails to cure the problem; you need a valid prescription for this.
Blood Sugar should be checked regularly. If diabetic then get proper treatment from a
Diabetologist for best results.
Circumcision may be required if the prepuce is long, covers glans and the condition is recurrent or if you have diabetes.
Consult a General Surgeon in such a case.
If you are sexually active , your partner too needs to take the same treatment.
I hope this answer helps you to get a proper solution, please feel free to ask further if you need any additional information.
Wishing you an early and complete recovery.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT & General Surgeon
