Pleurisy is what he said was the cause of the pain from that lung lining on the ribs being swelled. But he said his best guess is it is because of a shingles bout without a rash. He put me on a week of prednisone and after the first day I felt like 80% better with the pain. No way to know 100% the cause but this doc said he has seen this situation many times in the ER and Urgent care and writes it off as a shingles related thing. I tend to agree with him as the pain had 2 weird things, you could barely duplicate it by pushing or poking anywhere, and secondly the pain many times shot out all the way from spine to almost sternum. The shingles virus attacks the nerves and comes out from the spine so it sounds logical. No other good explanation I guess.Schmalts, look up "Pleurisy", in 2019 pre- Covid, one afternoon I experienced sharp pains in my left side. It all started around late afternoon and by 3 am my wife was taking me to ER. We thought for sure I was having a heart attack. The ER docs ran all kinds of tests and could not figure out what was going on, they called in the cardiac team and ran a bunch more tests on my heart and they all came back normal. My blood pressure was normal, everything checked out normal. Every time I took a breath I felt a stabbing pain on my left side near my heart. The admitted me into the ICU and 3 days of testing and observation with no conclusion. Finally on my 3rd day they had a "traveling" Doc come in to see me and he suggested I might have "pleurisy". In a nutshell, Pleurisy is an inflammation of the membranes that surround the lungs and line the chest cavity. The result is a sharp pain while breathing. In my case they finally gave me a steroid that attacked the inflammation. I was better within a week.
I have never had Shingles so I can not compare but your brief description matches what I experienced.
Best of luck, let us know how everything works out.
I have also heard the vaccine can kick your ass pretty hard from co-workers
