I have IC and I have just started exercising; afterward, I have a thick creamy white discharge and the intensity of burning increases from my IC. Could this be because of the exercise?
Exercise can increase discharge in general, but I am not sure about your specific symptoms. You might check with a doctor about the possibility of a yeast infection as well.
Here is the health central site on IC: Interstitial Cystitis
You also might want to check with the IC Association and see if they have any answers. Good luck!
