have all the same symptoms. my IBS symptoms are never the same, they change constantly, i can't keep up with it. one day i'm constipated, one day it's diarhea all day, sometimes it's both. i've been working out and feel sick, dizzy and headache, neck pain and i've been told it's cause of dehydration so i have to up my water intake before and after a work out and because of having diarhea you will need more water than usual. if there's no sign of infection then i'm sure you're fine but if you are that worried you should talk to your doctor about it again. i also had a UTI about a month ago which is suppose to be common with IBS cause of the amount of diarhea, have to be real careful with cleanliness. the lower abdominal discomfort sounds like the UTI could be coming back so definitely talk to your doctor about that. you should always talk to your doctor about anything you feel even if it's minor if it's bothering you then it's important. i hope some of what i said helps View Thread
