hi, 3 month is still a relatively short time and you body is still adjusting to a major operation, I am nearly 12 month from left hemi colectomy and resection , and still get some discomfort and sometimes bloating on left side , but scans so far have come back as everything is clear and ok. I have also read on here people who are experiencing this longer than 12 months . so I presume everybody is different and our bodies all recover at different rates... well thats what I am telling myself...
