Thanks for your question on Health Care Magic.
I can understand your concern.
Chest pain (needle type) on coughing in
bronchitis patient is mostly due to
pleurisy (inflammation of pleura).
And most common cause for pleurisy is infection.
So possibility of lower
respiratory tract infection (LRTI) is more in your case.
So get done chest x ray to rule out LRTI.
You may need antibiotics too along with
ibuprofen.
Better control of bronchitis is also needed.
So start inhaled bronchodilators and inhaled corticosteroid (ICS) for better control in bronchitis.
Don't worry, you will be alright.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
