Hi. This morning I had a coughing fit from a cold I m fighting. With my last forceful cough I felt a pop very low at the bottom of my tailbone. Since the pop I get a severe stabbing pain there when I cough, sneeze, blow my nose, or laugh. If I m standing up and feel a cough coming, I ll use my hand to put pressure on the bone and it won t hurt as bad. Pressure does cause pain, but not as bad as coughing without pressure on the bone. Could this be a pulled muscle on my coccyx?
