I tend to have a lot of pain in these 2 areas. Usually it is a dull pain in the back but with sharp pains in the pelvic area. They always happen at the same time though! I haven’t been checked out for anything yet. I do also have tingling in my back near my “chicken wing” bone. I don’t know if that’s related or not. Is this a common sign of ovulation? (I ovulate tomorrow) What else could it be? I haven’t kept track of what time of month this happens to me but will be for now on. If it matters, I am 9 months post partum.
