what is the milky white discharge when I pee. I'm passing a kidney stone and have been drinking 2 gallons of water a day, as well as laying on a heating pad. It all seems to be moving the pain along at a rate I can handle, but, today I started with this discharge. What is it?
A penile discharge is usually related to urinary tract (kidney/ureter/bladder/urethra) irritation.
It is commonly associated with various STDs and a handful of other issues (***including irritation due to kidney stones***).
If this is the first time you've experienced this discharge and you are not at risk of having a UTI/STD then it is most likely related to your stone. I would recommend simply calling your normal primary care provider (family doc) and mentioning the new symptom to him/her to be safe.
Good luck, I've passed stones before so I can relate to how it feels :S
