You could go ahead and ask how much of your colon is affected, how bad it is, etc etc.
Asacol is a long-term medication and you need to stay on it even when you're better. You could also consider adding natural supplements and a probiotic.
Well, pred side-effects get worse the longer you take it and when you come off of it they should go away. I don't know if the leg cramping is normal. And I don't know about
the period because mine didn't always happen in the first place. But the others are normal.
I know some people here use Entocort instead of Prednisone because it has less side-effects and I believe it is safer. Also, if you catch flare-ups early (like in the constipation stage / bright red blood and not the darker stuff) you can go on rectal medication to help stop it. You might consider starting that anyways, because while it doesn't treat your whole colon it will at least help the bottom!
We'll be happy to answer any other questions! =)
PS: And as for the Chron's thing, my doctor did an EDG (I think that's what it's called... where they put the camera in from the top end of you XD ) at the same time as the colonoscopy to rule out other things.
