I have abdominal pain but not the same pain as when you have food poisoning. The pain is like on the muscle and internal organ, when I poke my finger it hurts around the belly button. Yesterday I had low fever and hot and cold flush with sweating. The pain is constant,but worse when standing up straight, walk or move around in bed. When walking I have to be very slow and hunch like an old person and it is a bit less painful that way. I am 27, and had my 2nd daughter 6 months ago normally but my period has not yet returned (probably because I am fully breastfeeding). I don't normally get sick, this is the weirdest thing that has ever happened to me. Today the abdominal pain is still there but I no longer have fever.
