I know mate .... The French Paramedics broke two of my ribs attempting CPR. Fvcking agony for weeks.
Top tip I got from a physio was if I felt the need to cough or sneeze ~ Hug a pillow or large cushion to your chest before you do cough/sneeze. It does work and it makes it less painful.
Oh and hugging a wummun instead doesn't work .... AND the wummun usually objects to your snotting or hawking down her back!
