Does anyone else have a constant everyday feeling of pressure or knot (not painful until needing to poop)in left side abdomen. It gets worse before a poop like it's in my colon. I've have ibs-d for 20 yrs and in the last year I'm more ibs-c but it goes back and forth. And I've never had this constant feeling until now. I'm just curious if anyone else has experience with it. Thanks
