Christine~I think they are different...an abscess has bacteria/inflammation and a hematoma is more like a bruise on steroids.
I have had abscesses without a fever
in fact I didn't have a fever with the worst one I had a few years ago
An abscess needs to be surgically cleaned and is usually done under anesthesia (at least with my docs it is).
Crohn’s dx 1989
some terrible years before my
temporary ileo in 2001
Proctocolectomy w/end ileo in 2008
