So I will preface this by saying that sometimes this happens to me randomly. I would guess once or twice a year. It used to be more common when I was in my early twenties and I went to see a doctor about 6 years ago about it and they couldn't find anything. Since then though, it's rare that it happens to me.
It always occurs when I am sleeping and I will wake up and take a breath and get pain in my chest/back. Tonight it was the left side. I got up to pee, stretched a bit and it subsided but each time I woke up this would happen.
I guess I am more concerned about it now because I am pregnant. I did have some lower back pain last night after we took the dog for a walk so I don't know if it has anything to do with that. Pain is better now that I am up and moving around but I wonder if it had anything to do with how I was sleeping. Have any of you ladies had this occur during pregnancy?
