Well, this bump can be from many, many things.....
It might be a hernia, a sebaceous cyst, a inflamed lymph node, an aneurysm, a mass......lots of things.
The good news?
A simple physical exam and, possibly, an imaging study like an MRI should be able to quickly pinpoint the cause of this painful bump. If this doesn't narrow it down then a biopsy can obtain tissue for microscopic diagnosis.
So. What is the take home message?
I do not like that this bump is painful. The best course of action is to have your MD take a look.
Make sense to you?
