Folicullitis is usually from staph. Under-skin infection may be from staph or strep. Infection usually invades under the skin if there is any (even slight) skin injury, fissure
If it was contact dermatitis (soap, new clothes or washing detergent), there wouldn't be under-skin fluid, I guess.
It may help, if you check in google using "staph scrotum", "celullitis", "staphylococcus groin", "streptococcus groin" and related terms.
A related discussion, Staph skin burn?
What could the fluid possibly be? It was very very thick fluid and was deep in the skin.
The burning continues. My derm didn't see anything wrong and doesn't know what it could be. Everything is red and really really burns a lot. no lesions or anything like that though.
What could the fluid possibly be? The burning is quite painful. Not just a slight burn, but a serious burning sensation.
No, it doesn't sound like staph. It also certainly isn't jock itch. Bumps on the skin would not explain the scrotum's being bright red, groin burning, or folliculitis elsewhere. In other words, none of this sounds serious, but it doesn't add up. My advice is to let things alone (no rubbing or popping), to apply nothing but a non-medicated moisturizer twice daily, and to see the dermatologist, who can surely sort things out.
