i have had pains on and off now for around 6 weeks all over my abdomen . mainly on the left side between my ribs and hip .the pain varies from a pinchy stinging pain to a bruised feeling .it feels worse whenever i need to open my bowels ,eat or need to pass wind .sometimes it feels like its a pulled muscle but sometimes feels like it's right inside .my doctor (without testing me )said i have diverticulitis disease and gave me antibiotics which didn't do much ,then i went back he said it sounds like i have fibromyalgia with ibs .now 2 weeks later im still in pain but now have a thick fishy smelling mucus when opening my bowels which can sometimes be itchy .im 25 and female .
