Dermatology Questions? Ask an Online Dermatologist.
HI and welcome.
This type of bump you described can be due to sebacious gland inflammation due to previous infection. It usually go away in couple of weeks however if it stays and changes characteristics it need examination by a dermatologist. For now i would suggest just monitoring of the bump as you have no pain or itch.
Let me know if you have further questions.

It can be sweat gland inflammation. Try to keep the area dry and improve hygiene. It does not seem to be anything of serious concern.
No, it does not look like a wart. Warts are not vesicular, they are verrocous.
