Hello! Thank you for the query. Its hard to suggest anything as you havent even mention where is your pain located and if there are any other symptoms. Generally after every surgery there is a risk of fluid collection inside the abdomen (pus or blood). This should always be ruled out if abdominal pain appears after some time from surgery. Other possible symptoms of such fluid accumulation is fever, bloating, nausea, diarrhea or constipation. Diverticulitis usually gives lower left abdominal pain and I`m pretty sure you can discriminate diverticulitis pain from other pain (as you have had it before). I hope that you know what diverticulitis can turn into. Sooner or later, diverticles inflammation will cause intestine perforation. That is why, when diverticulitis keeps recurring, surgery and intestine removal is advisable. I suggest you to visit your doctor and have blood work (CBC), CRP level, urine analysis and abdominal ultrasound done. Please consult general surgeon and consider further surgery of your large intestine. Hope this will help. Regards.
