I have the same thing, more like stained ribs, but lying down or turning in bed is excruciating . I was a youtube video where you make a nest either side of you with pillows, then when you need to turn in bed it's more just a gentle roll as the pillows support you. I tried it a couple of nights ago and it was much more comfortable . Doctor in A & E told me takes exactly six weeks to heal . Ive to go back if no better. Only reason I went was I have Osteoporosis so was concerned I had broken more than one ! Take care .
