Hi,
There are many possible reasons for a bump over the penis but I will cover the 3 most important ones -
- Skin bumps or
rash due to friction
- Fungal Infection
- STD
A skin bump or rash due to friction is seen when one wears tight clothes or sweats a lot.
This can cause some swelling as the skin gets injured. This can cause swelling and some bleeding. If the swelling persists, there may be a greenish pus that can form as well.
A fungal infection of the crotch which is also known as
tinea cruris can present with some bumps. However, there would likely be some itching as well. Rarely, some pus may form which can be green in color.
STDs or sexually transmitted diseases can happen when one has unprotected sexual intercourse. They can present in various ways. Getting this diagnosed would need an STD panel test.
To rule out other causes, you would need an in person examination. Based on the diagnosis, the doctor would suggest either antifungals or a skin conditioning cream to help.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Vignan Rachabattuni
