HI. As you have rightly described , you may be having a hernia with obstruction of intestines sometimes only. The pain in abdomen with sounds of intestine. At the same time the other symptoms leads to Pelvic inflammatory disease
needs further investigations , at least a sonography
, may be a CT scan
of whole abdomen after preparation.You do need a long course of antibiotics. Need to see a General Surgeon
at the time of your pain and sounds in abdomen to get a clear-cut diagnosis.
