Hello, this is Dr. David. I have read your question and I'm ready to help.
I am sorry you have had a bad case of bronchitis.
you should get blood testing to see if you had an influenza viral
infection or flu infection which might need antiviral therapy to help you get over like Tamiflu.
I think you need to see a pulmonologist lung
doctor instead and get a lung CT scan
you might need mucinex to help break up mucous in your lungs to help you clear it.
you might need oxygen therapy in the short term if you are not able to get enough oxygen into your system
I hope you are not smoking.
I am more worried about your shortness of breath.
I would see a pulmonologist and get a chest CT scan and pulmonary function test and see if mucinex can help
and get testing to check for influenza infection or flu to see if you need tamiflu therapy
let me know if you have questions.
