Hello and welcome to HCM,
The pubic area is rich in hair follicles, sweat glands and sebaceous glands.
Any infection or inflammation of these skin structures can cause bumps.
These bumps can cause pain, bleed or collection of pus due to infection.
These lesions can bleed when traumatized (while shaving etc.).
A STDs are characterized by ulcers, rashes or lymph
nodes on the external genitalia.
You can apply a topical antibiotic
cream on the lesion.
Avoid trauma to the affected area.
Thanks and take care
Dr Shailja P Wahal
