I never feel sick or get a temp when I have an abscess. It just hurts, a lot. Try taking warmish hot sitz baths, or put moist heat on it. Try sitting on a heating pad with a barely damp towel on it. Usually if it's an abscess, moist heat will bring it to a head faster.
Dx'd w/ Crohn's in 1979 at age 13. Bad flare 2008 but no health insurance so I dealt with it. Colonoscopy in July 2009 caused a perforated colon, emergency bowel resection. 2 fistula's, perianal and perivaginal.
Humira, probiotic, a multivitamin, Glucosamine, D3, calcium, potassium, magnesium, zinc, and fish oil. I also take Tramadol 50 mg and Klonopin (for anxiety) as needed.
Life may not be the party we hoped for, but while we are here we might as well dance!
