I'm 32 weeks and for the last 6 weeks or so, on and off, the skin and area around my belly button in about a 5cm square has been really sensitive to the point of soreness, where I've nearly punched DH in the face every time he tried to rub my belly
(granted, I have told him not to do this and why, about 1000 times)
There's no obvious sign of a rash / skin stretched too thin etc, and I spoke to my Dr last week who said it was probably normal with the stretching etc, but I should keep an eye out in case it turned in to an umbilical hernia, which I then foolishly googled 
In the last couple of days it's got worse, with yesterday throwing in itching, the only way to remedy it was in the shower with one of those shower puff things. The itching has eased off, but i woke up with what feels like muscle soreness on one side
I can't work out whether it's because the baby has moved (there's a a definite shift gone on in the last 24 hours) or something else. Everything else seems to be fine (movements are normal etc) but after my googling I'm now convinced it's something weird (as always, bless the internet)
Has anyone had similar? If so, did it go away / what did you use to try and ease it off?
