hi my name is karen im 20 years old and ive had this problem for a couple years now i have frequent urination sometime an hour apart but most of the time can be for 10 minutes to maybe 30 minutes apart . hope i explained that alright but ive been to the hospital and they did a urine test and found no infection so they asumed i had over active bladder but the medicine they gave me isnt doing anything and also before the hospital ive been to urgent care and all they gave me was uti medicine but tht didnt help either . i did have a uti once though while this was going on but got medicine and it helped the uti but still was urinating constantly and its affected my jobs too and also dont know if this is related but now recently ive been so tired where my eyes get heavy even when ive slept enough and also been having small dizzy spells well more light headed but same thing i guess . and about the urination thing ive tried over the counter medicine and nothing helps i really need help this is driving me crazy .. i dont know what to do . i wanna know whats wrong with me before it gets any worse. oh and ive tried not drinking pop ive tried just drinking water and aslo cranberry juice somethimes and i still urinate alot.
