Something similar is happening to me. I went 5 years having constant explosive diarrhoea with alot of blood. I suffered for 5 years with my specialist telling me nothing is wrong. I found a new specialist in December and by January he found Crohns in my colon and small bowel. Days after being diagnosed I started to feel constipated and bloated. I still go to the toilet about
3 times a day but everything is solid and doesnt really want to come out. Im not on any medication for the Crohns until I see my specialist again 1st week in March. I just cannot understand how i have suffered this long and then all of a sudden its the exact opposite
