I got pain under my breasts for a little while, it was sort of in my ribs. It would have been around 33-35 weeks I think? My skin there felt as if I had chafing there - burny and sort of numb like as if I had rubbed the area repeatedly. Is that what you are getting?
If so, I found that when she started to engage it eased a bit. I used to walk around trying to hold my belly up lol. Sometimes I even tied a scarf around my waist to pull up my bellly and this sort of helped a bit.
