I have had flu very badly, I think it was H1N1.. in bed for 3 weeks totally poleaxed .. It started with  tracheitis then suddenly went into full blown flu .. Took antibiotics .. and Tamiflu .. After the flu subsided I had a recurrence of  the tracheitis symptoms and then it turned into bronchitis (with bacterial infection) and  was put onto antibiotics again .. After that, I had another course of antibiotics , as it had not cleared up .. now after this course has nearly finished, I am still  coughingup loads of phlegm and have chest pain and my trachea feels raw again .. but at least the green mucus has gone .. it is clear now .. but  I still feel very uncomfortable and heavy in my chest and am shivery .. I am also having periodic quite violent , painful muscle spasms in the trachea that goes through to my back and  is quite scary but lasts only a few seconds. I notice that my digestive system is affected by this too, as if there is pressure on my stomach from the lungs.  I am 61. My doctor said there was no pneumonia.. although I have had pneumonia in the past. I fear there is something else going on.. Or is this merely the classic after effects of severe flu. Thank you
