Hello,
You are having rashes on the anus. You are working at a construction site and the rashes occur recurrently. Your rashes are suggestive of
heat rash, take care of your hygiene, avoid wearing undies on which you have sweated. Take regular bath, clean the affected area with antibacterial soap.
You suggested to apply
Hydrocortisone ointment to prevent itching. In case of
fungal infection, applying
Clotrimazole ointment works well. Fungal infection occurs in warm, moist area. Keep your private area dry and clean. Wear loose fitting cotton clothes. You can take a course of oral anti fungal for relieve.
Do not share your clothes, towels and toiletries with anyone. Taking antihistamine, at bed time will help relieve symptoms. If symptoms persist, get clinically examined by a
urologist, get STD tests done to rule out shingles, herpes, etc. You will be accordingly treated with antivirals / antibiotics. Stay away from addictions if any.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
