Hi. I ve had a bad cold for a week now and during the last 3 days, when I sneeze (and that happens a lot) I get a sharp, diffuse pain, that feels almost crackling/popping across the front of my chest/lungs. It takes a few minutes after sneezing to subside and feels quite tender for a while. I am 38, female, non smoker, 57kg, otherwise healthy. What do you think this pain could be?
