I know it is stressful waiting for results. I went through that yesterday. It is exhausting. Thank God everything turned out clear. As for rib pain, I have always had some on the side of my mastectomy/reconstruction. Perhaps this is the cause of your pain as well. After everything our bodies have gone through, there is bound to be a lillte shifting. Like a house settling into its foundation. Did I just say I was as "big as a house"?
I will pray for you.
