Genital zit? Or something else

Hello,

I have an object that is a substantial hard bump at the area where the side of my scrotum meets my body.  It was dark and blood filled at the top so I popped it and blood came out.  No pus or other fluids, just blood.  And the hard part underneath the blood is still there.  Immediately scabbed over.  

I have a guess it's an inflamed hair follicle (It is right in the crook of where the scrotum meets the body and there is a ton of sweat there when I exercise).  I just want to make sure that it's not herpes.  I did have protected oral sex with someone who I didn't know, but her lips never got to that area

So I doubt it is herpes (doesn't itch at all and I had to pop it, plus there is only one, not a cluster, and it's in an area that isn't touched often with the mouth), but does anyone think that is a good guess?

Thanks

Hello,
This kind of bump can be a swollen lymph node, a sebaceous cyst or a boil. Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection along with other numerous causes.
Sebaceous cyst is a closed sac or cyst that with a fatty white, semi-solid material called sebum produced by sebaceous glands of the epidermis. It is usually painless but can become painful if infected. Then antibiotics are needed.

Boils are caused by infection of the hair follicle be staph aureus. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
