five years ago, I had rectal cancer. So after radiation, I had my rectum removed with temporary illiostomy.

eight months later it was reversed. No problems other than irregular bowel movements. From extreme, diarrhea, to lots of straining to constipation, to slow interrupted movements, (back and forth to bathroom during 3 to4 hours. I have been taking psyllium tablets 3 daily,  Miralax in different dosage, was put on Linzess. To make a long story short, now it like a chronic constipation. Tests show that there are no blockage, but am f.o.s. I have no contractions to empty out. Sitz marker  test shows 18 marker in the colon.  My surgeon wants to put in a permanent colostomy.  Says there are no obstructions, he just can't explain it, seems like I am his first such case.

please let m know if you have had similar experience, what you did, who did you see. I would led appreciate any advice, suggestion or recommendations. Thank you !
