Hi. When I have a cold and cough hard, I sometimes get a painful stinging, prickly sensation in the lungs (i think), which radiates all across my back. A couple of days ago, I swallowed down the "wrong tube" and coughed hard, and that happened again. This time it was very painful and the cough was so hard that pain radiated down my arms to my hands. The pain goes away quickly but leaves me sort of beaten up.
