I'm still on postop for bladder surgery...can't have any straining at all, so he has me taking 2 stool softeners and Mirilax before bedtime...it sure works.
But I have a feeling this is your MS not making those muscles work to unload. It's best to call a doc...don't let that stuff stay in you too long...I know it's been too long when I feel too uncomfortable and I look pregnant...
