The reason you have no diarrhea is because the inflammation is still low in the rectum....a very good sign...remember it starts at the rectum/anus junction (for loss of the proper tern), and spreads upward.
When you tapered to one every 3 - 5 nights ...did it vary from week to week or were you consistent...every 3rd night for a few weeks, every 4th night for a few weeks, every 5th night..etc.?
Moving is very high stress and sometimes the high adrenaline helps to mask the fact that there's inflammation happening until after the severe stress has passed. Then it seems out of the blue.
Low in the rectum flares are hard to sometimes recognise because they aren't the norm until something more obvious happens. In your case, bleeding. It means the tissue is quite inflamed to the point of friability (fragility).
So, you're back to square one....stay on the enemas nightly until you have NO bleeding. Stay on them for another week then go to every second night.
Treating and maintaining is a constant. Try to strive for recognising symptoms, treating early, a tapering schedule that works for you and maintenance that your body will pretty much rule anyway. If you taper too soon, you may have to go back to the last dosage whatever it may be at that time.
One suggestion....whe you insert the enema, squeeze a bit and then withdraw it to just the inside of the anus and start squeezing there then fully insert it. That'll get a good concentration where you need it.
Hang tough...the first year or two of figuring out the meds and then using them long-term is a pita (pain in the arse) and expensive... but the rewards are worth it. At least that's what my 19+ years experience of hardcore 5ASA meds can attest to.
Keep us posted as to how you're doing.
