i was diagnosed with diverticulosis not to long ago thru an barium enema, wasnt to pleasent but nothing compared to the symtoms i have been getting nasuea, severe cramping on left abdomen, bad bloating, sour taste in mouth, diarhea and what not pretty much every symtom iv had including what i think blood in stool and seems to be getting it more now every time i go before it wasnt as bad my question would be is how do you know if it is blood and how bad is it when it is blood?, like the blood is in the stool and its light blood dont think i have a hernia either its not outside the stool loose but intertwinged with it one was attatched to what look like the outer layer of a tomatoe but havent ate none and when i moved it it smeared red but the outer thing was still intact
