Hello, i recently had a  lump in my pubic hair that was hard and firm, somewhat nodular, that scarred pretty bad as i tried to pop it like a pimple. Recently i again developed a lump now at the base of the shaft of my penis in a hair follicle, i pulled out the hair but it did not get better. It has been there for a few days now and it feels very hard like a nodule and is the size of a pea, it grew i size after i attempted to pop it. I am worried it may be an std because i did have unprotected intercourse about 2 months ago. Please advise.
HelloThanks for query. To get pimple like hard lumps at the base of the penis are Sebaceous Cysts. The skin in genital area 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. Take antibiotics like Doxycycline and anti-inflammatory Chat Doctor. Ensure to observe proper personal hygiene by cleaning genital area with soap water twice daily. If it persists even after taking medications you will need to consult qualified General Surgeon for clinical evaluation and further treatment. If needed he may advise you to get it excised in Toto (Completely along with the sac).
