I had a perforation that contained itself as an intra abdominal abscess. My symptoms where generally feeling unwell, extreme dizziness, sweating buckets, raising CRP from 90-280, nausea, diarrhea, weight loss, pain and palpable mass in RLQ with referred pain into psoas muscle (front of thigh). It was picked up on CT scan and I was treated with 1 week of IV antibiotics and 3 weeks oral antibiotics. The abscess shrunk and infection cleared but I needed surgery in the end due to the damage and residual collection of fluid. If you suspect an abscess you need bloods taken and a trip to the hospital before it becomes worse. Most intra-abdominal abscesses need drained. Hope you get some answers soon.
