In November 15 my colon ruptured, leading to emergency surgery. Afterwards I tore a large hernia and ended up having colon resection and hernia surgery a few weeks early-about 6 weeks ago. Last week had CT Scan and was told things looked good, then yesterday after lunch I began developing upper abdominal pain, which got better, but after dinner it has gotten worse and no bowel moement in 12 hours. Scares me as this is how everything started in November-pain and no BM for two days and then boom, but then pain was in left abdominal and now upper. Should I be worried?
