yoy must had pneumonia
with parapnuemonic effusion and a chest tube
would have been inserted
i think you are havng a neuropathic pain
in all your chest ........cause of that tube ....you can ask your doctor for high potency pain killers or gabapentene
you feel tired cause of a long illness take multivtamins coz you must a lot of antibiotics
go for a follow up to your doctor for chest xray ...for any refluid...
