M.S.
I have been there, had the tests, and told I was fine. Next time it happened, I went to the chiropractor. I had 2 ribs out in the back, and 3 in the front from coughing and sneezing. I literally used to wake up in panic attacks from it every few months. Now, I just wait for the chiro to open and meet him there. It's sore for a few days afterward, but that's all.
