I'm 30 weeks pregnant. About a week ago, I started to feel a sore, chaffing type feeling under my right boob. I thought my bra was perhaps digging in or rubbing and expected to see some obvious reddening of the skin under my bra line. I am wearing non wired bras and have been for a while. My skin isn't red or sore looking and the bras dont actually feel that tight. I've changed bras to a soft crop top and tried putting a barrier cream on. However it hasn't got better and the pain has spread a bit further over my ribs below my right boob. It feels like it is on or under the skin, sore, a bit of a burning type pain. It doesn't feel like when you pull a muscle. I can cope with it but it's a bit distracting. I'm now wondering if it's actually my ribs being stretched, or rib flare. Anyone experienced any thing like this? (my blood pressure is normal and I have no symptoms of any thing else). Thanks!
