Hello Thanks for your query,based on the facts that you have posted it appears that you have what is called as ebaceous cyst. The penile skin is rich in sebaceous glands and hence prone to get more sebaceous cyst due to accumulation of sebum beneath the skin. Normally they fade away without treatment however they need to be treated if increase in size or get infected. Please consult qualified General Surgeon for clinical evaluation to confirm the diagnosis and for further treatment. You need to take broad spectrum antibiotic like Cefexine along with anti inflammatory drug like Diclofenac twice daily.along with topical antibiotic ointment like Neosporin twice daily. Ensure to wash your genitals with warm water twice daily Ensure to avoid sexual encounters till it heals up completely. Dr.Patil.
