Hi I m a 44 year old healthy active young gal. I have been feeling on and off like a bladder infection coming on since July 2014. I went to my primary Dr. and did a urine test, no bacteria found. Symptoms are now with a bit of a burn. Tested a few months later and I have trace blood in urine and feel spams in my private area. I have seen a Urologist, did a Cystocopy all is clear bladder, kidneys, urethra all good. Still have trace blood, burn and spasm? I have no answers given, any leads you can give me?
