Hi Beanley...have had the same thing on and off for over a year. It was finally decided that it was due to my age (I'm 63) and the outer urethra tissue was dry and frail due to the lack of estrogen. (had a hysterectomy at 23). I use Estrace cream when it hits me and that seems to help. If you are young...I doubt that this is your problem but just thought I'd mention it! I don't have any burning while urinating either...it's just there and it comes and goes no matter what I'm doing.
