I got it when my tummy had swollen up from some gastro problems, and when I got to coughing, my stomach muscles were stretched out and could not hold in the spasm, so that created the hernia
. My belly
button was painful for several days, and when I pushed on the swollen part, it hurt. Then general discomfort went on for, oh, two or three weeks. I now have a malformation there, eventually I'll have it fixed for appearance-sake only, because it doesn't bother me at all now.
