Okay, so have been on Estradot patches for about a year (50). For the past few months though, I ve been waking more in the night, having hot sweats though - and here's the thing - they're mostly confined to (tmi) my thigh and vulva area. So much so, it feels really itchy on account of the sweating. During the day it s all normal. Do I need a stronger patch do you think?
