I have been havin left sided abd pain for two weeks now with constipation on and off, my ct scans show very litlle dicerticulosis with now evidence of diverticulitis. it gets so bad sometimes to where it feels like someone is squeezing my side abdomen and i cant walk. it then just continues constantly with a dull ache all the way to my fold in my leg near my groin.it is only on my lower left side and is not getting any better. what is this if the dr supposedly says its not diverticulitis.
