I think this is called 'rib flare' - a stabbing, burning pain round the ribs. For me it's round the right hand side from front to back about the level of the bra line.
I had exactly the same thing in my first pregnancy, and it was horrible and constantly uncomfortable, but at least it didn't hit until the the 3rd trimester. This time round it's hit at 16 weeks FFS!
Has anyone found any successful ways to manage the pain? Am wondering if it is worth seeing a professional (physiology or something). I can't face 6 months of this!
