Hello dear I understand your concern Your symptoms could be due to the cystic acne, infected sebaceous gland, hair follicle infection. I would suggest to consult the dermatologist and undergo clinical examination to confirm the cause. You can also use the premium service of the HCM in which you can upload the picture of the pimple at the report section for better management. Doctor will give following advises: a short course of antibiotics after a thorough examination of the area anti inflammatory drugs like ibuprofen Apply mupirocin ointment Take sitz bathe with added betadine Avoid soap bath Maintain proper pelvic hygiene Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
