Last evening after a bout of severe pain while attempting to empty my bowels (which were loose but not D), I suffered the usual cramping and took it easy for awhile. Before I went to bed I had a lot of mucous and a little bloody discharge, again not unusual for a bad attack. I awoke this morning, went and brushed my teeth to find my toungue was black! When I spit in the sink it was black and my tongue had a wierd black coating on it. I had this happen once before after having a bad episode and attributed it to something I ate. Last night, I don't think it was due to eating, I had a very bland dinner. Has anyone else had anything like this? My husband thinks it is over production of acid? Please help!
