I am a lucky sole that gets this frequently. I beleive that it is an urinary tract infection (UTI). They will ask you for a urine sample . If it is they will give you some antibiotics for about a week. You should start feeling better in a day or two. You do not want to mess with it though. You can be hospitilized if it gets bad enough and it can cause damage to your kidneys. Good luck!!!
about six months ago i experienced this...I have had UTIs before, but never like this. after several doc trips and cultures that showed no infection but blood in urine, several meds, a kidney stone scan, etc., i was finally referred to a urologist. he found that i had bladder spasm and nephrocalcinosis, which was treated with meds and cleared up almost immediately. my symptoms were burning when urinating and lower back pain that lasted almost three months. if this sounds like you, def go to ob/gyn and try to get a referral to a urologist. best of luck!
