My daughter had surgery a little over a week ago for slow onset CES.....right after surgery her bladder pain was gone and remained good for 4 days....then the bladder sensation of a full bladder returned and has gotten bad again.....this coincides with her period starting up this month. We noted over the months between injury and surgery that things were always worse just before during and a few days after her period.....is it a normal for menstrual problems to cause the bladder pain to become more severe during that time each month with CES? Will this go away or should we put her on hormones to shut her cycles down?
