Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain red spots on roof of mouth along with a history of coughing and throat infection
along with bronchitis
seems to be due to infection and inflammation of the roof of the mouth..
It is a commonly seen condition during throat infection..
I would suggest you to take a course of antibiotics, anti inflammatory painkiller like Ibuprofen
, do warm saline gargles and steam inhalation..
Use a humidifier in your room..
You can take anti allergics like Benadryl
and cough suppressant containing Dextromethorphan
Avoid spicy and chilled foods..
Sop on plenty of warm water and other warm fluids..
As the Inflammation will reduce the bumps will gradually resolve..
Hope this information helps..
Thanks and regards.
