Welcome, Palace. I'm sorry you needed to come here, but glad you found this board. You'll find a lot of information and support here.
I Googled "chronic active colitis" and all the results I got pertained to Ulcerative Colitis, so it just may be that you have UC. If so, it's a chronic condition, curable only with surgery, but usually managable with medications. Check the information here at healingwell or at the CCFA web site to educate yourself so you'll be ready for your appointment with the consultant.
Moderate to severe left-sided UC (21 cm) diagnosed 2001.

On Prednisone then Entocort 2001-2006 with only short periods off.
