[|Human|] My husband had a thoractomy about 7 weeks ago. He was healing nicely, but then got a cold and began to cough a lot. When he coughs it is very painful especially around the sternum, and there is a thumping noise loud enough that I can hear it. This thumping is quite painful and sometimes continues after the cough subsides. XRays and CT Scan are normal. What would be causing the pain and thumping?
[|AI|]  Respected user, hi I evaluated your query thoroughly.* Cause of pain is due to irritation of Intro thoracic nerve endings, scarring post-operative, ligaments / muscle stretches, other lung related issues.* Thumping noise may be due to sternum instability post-operative Hope this helps you.
