Mega flare up, any suggestions?

I have been experiencing a pretty bad flare up the last two weeks.  It started gradual, not making it to the bathroom in time about twice a day.  Now it is full blown flare up.  I only make it about 2 hours or so before running to the bathroom to pass only mucus and blood.  I'm having cramping on the left side which has now moved to the right side.  My tummy is grumbling lots.  I have switched to a bland diet as of Tuesday.  Rice, potatoes, gluten free bread, water and not much else.  My GI doctor is out until Wednesday.  I have an appointment late afternoon with her.  In the meantime, I'm trying to make it through the weekend and not have to stay next to the potty the entire weekend.  Any ideas would be greatly appreciated.   I'm really concerned with amount of blood I'm passing a day.  Its averaging about 7-8 trips to bathroom a day.  Mostly blood and mucus with little to no poo.   I did take Immodium A-D, only one a day to control urgency.  I'm afraid it will cause constipation.  Help!  I'm at my wits end.

I think I would put a call into my GI and see if she can give you some advice to keep you going until Wednesday. She may be able to prescribe something that will help you. Waiting is so difficult when you're feeling terrible. I am sorry.

Steroid foam enemas are helpful and easy to retain.

Take 70+ mg of Prednisone, just one day, blast it to an end. Seriously? Well yeah, If you go the the ER, as I did, after a massive round of flaring, bleeding etc, the ER doc, if they are any good, will issue an order for 100mg of prednisone to stop the flare. No tapering needed. Worked like a charm.
