Am I too impatient about healing, and does this "diagnosis" sound right?

After months of suffering and trying to convince doctors that my diarrhea wouldn't just "go away with imodium" I was finally c-scoped last week and imaging showed inflammation/ulcers.  I was started on UC treatment of asacol800 3x daily plus daily sulofalk supp and enemma.  The biopsy came back showing not indicative of IBD, meaning no markers of autoimmune.  They did say the bipsy showed signs of ischemia (lack of oxygen to tissue in colon, causing death of cells).  The GI Dr's "hunch" is that this is not autoimmune, but was caused either by an infection (that never showed on my numerous blood/fecal tests) or from the MASSIVE amounts of cipro/flagyl (antibiotics) they used to "treat" my diarrhea that I kept pestering them about.  He told me that once this inflammation etc has healed it is not likely to come back...then told me to follow up because sometimes this can be an early warning sign for IBD, and or trigger IBD.  *** am I to do with that?

As far as my healing, I've been on the meds for about 8 days now.  My BM's have decreased from 8-15/day prior to meds to about 2-4 per day.  The thing is, my guts are still constantly cramping and all of my bowel movements are still very much diarrrhea, as in, no formation at all, liquid, pure, yellow, nasty liquid.  This is my first flare, and hopefully my last as I am not showing signs of it being autoimmune, but, how does one go about  healing from a flare>  Does my progress sound sufficient?  Should I be focusing just on the # of times i have a BM each day and not worry about the consistency?  Any kind of time frame from you guys would be great.

P.S. I am also taking a probiotic (over a month) and just yesterday started taking metamucil fibre pills (starting at 1 per day) to try to bulk things back up. 

Thanks for the kind reply Kazbern. I was told the signs of ischemia were like signs of trauma in my colon, due to so much inflammation/adverse reaction to the drugs. They listed it as"signs of ischemic injury" which, based on what I could find on Google is less severe and slightly different than the diagnosis of Ischemic Colon. According to my GI who did the scope, upon visual scoping I presented as UC, with the sores, inflammation, etc. They are a bit puzzled that I had no IBD markers in blood tests/biopsy. I believe they are guessing as to what caused this mess.

Dr-A, my goal is to slowly build up to more fibre pills/day but wanted to do it gradually and not shock my system. Are there other ways? Any suggestion for me? Traditionally bulking foods have been too painful, so I am eating an easy to digest diet right now, admittedly low in fibres.
