I am with you on this one Glad Bag. I too suffer incredibly painful abscesses/fistulas in the geographic area you speak of.....hate is an understatement. I loathe them.
I currently have a horseshoe with 2 portals. Originally resolved by Remicade (10 yrs ago). Returned 2 years ago (mild) - knocked down by Imuran and antibiotics. Back this summer (severe) - no relief from Imuran etc; went to Remicade with some relief but have had a delayed reaction to second infusion (because of the decade lay off) so most likely headed for Humira.
GB.....are you strictly left with surgery now?
