Pulled muscle anyone?

Has anyone ever experienced a pulled muscle in their breast area? Doc said it’s side effect of pregnancy. I reckon it happened because I sleep mainly on left hand side and one day must have gotten up in a dodge way and it ripped (I remember it happening, ouch!)

Now, whenever I sleep and get up during night to turn, it’s a ripping pain again, or if I’m sitting on couch it is a slow pulling pain.

Anyone else ever had this? I heard it may be intercostal pains. But I wonder if it’s more common (hence the question) and because my breasts are growing at the same time.
