I am a scuba diving instructor and got bronchities while living on a small island in Central America and was given questionable treatment ('doctor' didn't even listen to my chest or give me a check). The cough went away and I carried on diving every day. 3 weeks later the cough came back over the space of 24 hours, I developed a high fever, painful joints and muscles and vomited regularly. Due to the lack of doctor I waited 4 days until the American doctor on the island was here at which point he diagnosed pneumonia and sent me to the hospital on the mainland where I spent 3 nights. 4 weeks on and I feel fine in myself (a bit tired and lethargic) but I still have pain in my left lung when I do any form of activity (even walking and talking at the same time hurts). It is especially bad if I cough or sneeze. I'm supposed to go back to work (diving) next week and I don't if I should. Are there any after-effects of pneumonia that could be causing this? I'm worried that I didn't get it treated early enough that I've done real damage, and am especially worried of pneumothorax when diving.
