bump under penis skin

About a month ago I notice a small 2mm hard bump under the skin of my penis shaft underside. This bump does not hurt. Nor has it grown or shrank. It is real noticeable when my penis is erect. I have read about sebaceous cysts but should i worry about something else? thank you

should feel something painful if it is, sebaceous cysts. Defiantly should go to the doctor tho get it checked out.

Hi,

This could be folliculitis, acne, pimples, fordyce spots or genital warts.

Nothing can be said with surety without having a look at the lesions and a clinical examination.

Do you have any other associated symptoms?

You could read more about fordyce spots at the following link -
