I'm now 36 weeks and the pain has almost entirely gone - it's still a bit sore but I can now sit, stand, walk and lie down with practically no pain. I'm so happy - it has been a long slog .
I just wanted to reassure anyone who has been experiencing the same as me (as outlined in this thread) that it does eventually go away. I was convinced that it would get worse as I got bigger but it finally went away after 12 weeks of pain!
The blue eye-gel mask (mine was from The Body Shop) kept me sane - it really did help ease the pain and I can't recommend it enough if you are getting the burning sensation on your ribs or if it is inflammed at all. I had two masks - I kept one on the top of my ribs and the other one in the fridge so that I could rotate them. The masks and lying down is what I think helped to get me better.
Just a thought, my stomach muscles have torn apart, also called divarification, because of the pregnancy (apparently it's more common in women who have had more than one pregnancy, although this is my first) so I was wondering if anyone else with this rib pain has also had torn stomach muscles - there could be a link...?
Rosa7, I don't know what I'm having - but you're right it does appear to be a boy problem - I will let you know when I give birth!
