This video explains it all. Extremely painful if I cough, lie totally flat and more.
What the hell is wrong? What have injured - is there some tiny muscle you could pull while your son is on your shoulders? How long is it gong to hurt? How can I treat it?
If I'm just sitting still, I barely notice it. I could even do a rowing machine or run without it being to bad but certain times of the day it's like 10 out of 10 pain and it's been 9 days.
