Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Bronchitis takes a lot of time to recover and only steroid and antibiotics may not help much.
Since you are shaky, weak,
dark circles around eyes and have
chest pain also indicate that you need the following in such a situation:
Clinical evaluation by your Doctor and may be a referral to a Pulmonologist for
second opinion.
Tests of blood for CBC, sugar and as needed.
C-ray of the chest as you have breathing difficulty and CT scan of the chest if needed.
Test of mucus/secretions helps in some cases.
Symptomatic treatment with
Paracetamol, bronchodilators, stream inhalation and so on as would be needed.
Specific treatment is possible only after a proper clinical evaluation, correlation with investigations.
Till then avoid people with viral infection.
Avoid sudden temperature changes zone.
Take bed rest with no visitors.
Hope I have answered your query.
Let me know if I can assist you further.
