Thank you for the posts. I will try the heating pad and see if that helps!
That was common with my last two pregnancies, from seven months to the end. I think both of my girls shoved their foot in my ribs and just kept it there. It was my left side as well. My torso just wasn't long enough for them to stretch out. :)
I had that same pain and it was because my daughter wanted to stick her little head right under there which cause it to bruise...a heating pad or warm rag will help with the pain :)
I have the same problem but I'm not sure why it happens or what to do about it. Hopefully this comment will bump your post up
