So for the past 3 weeks, I've been itching downstairs. I have to itch all the time! Almost a year ago I had my tubes tied. I thought maybe it was a ph balance issue but my mom and i were thinking now that it may be my estrogen levels being out of whack. Has anyone had this issue? Also if you live in Texas, do you know if healthy Texas woman's insurance will cover a check up to see if it is that?
