Hello, I have just gotten over some sort of viral illness that has left me dehydrated from nausea, vomiting, and very poor intake for two days. I m back to eating, drinking, and urinating again, but I have so many little sharp body aches all over my legs and this recurrent sharp, stabbing pain in my ribs on my left side. It s beneath the armpit but lower where my bra band would lie. Is this just another side effect of dehydration or is it something else? I m 30 years old, female, and a nursing mother.
