I've noticed the my underarms have become so sensitive. I've poked around making sure there isn't a lump (and there isn't), but they are just always sore. Mostly my left one and it's not the entire armpit, but the lower part. It almost feels like razor burn, but it's not red. Maybe its the skin rubbing against each other? I don't know. Anyone else have this problem?

Hey there--

I dont have this issue myself, but I have read that dropping estrogen levels can make us more sensitive to pain in general. Sensations that wouldn't have even been on the radar before now register as pain. I read of one woman who said "My hair hurts." So it may be something like that at work.

Meanwhile, have you experimented with good bras to make sure nothing is riding up and chafing there? Just a thought...

Low estrogen levels can cause dry skin. Mine was worst a bit lower than yours - more at my sides at the top of my ribs.
