Hi, I am new on here...found this site by search...but i have had a bowel problem now for 3 weeks. I will have diarhea for a day or two with blood filling the stool and the tp...then i will go several days without a bowel movement...then yesterday my bowels were very dark green (i have not taken any pepto or anything else that i know of that would cause this), then this morning when i got up my entire tongue was coated with a green film...I have went to the doc and have a ct scan sceduled and the colonoscopy sceduled later on this month...I was wondering tho...i had a botox session in the middle of April for chronic migraines..this has helped my migraines but about week after this is when i started having my problems..the doc does not think there is a connection...but i am just wondering....thanks in advance for any advice anyone can share. :)
