Hi,
As per you complain it seems that you are suffering from upper
respiratory tract infection and along with it there seems to be superseded bacterial infection.
In that case, the antibiotic is a must and if Doxycycline is not working you need to get antibiotic changed. As of now, you can start with supportive treatment to relieve the symptoms like:
-Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to make a lukewarm solution.
-Take a combination of decongestant like
Phenylephrine,
mucolytic like Ambroxol and anti-allergic
Levocetirizine and another combination of
Acetaminophen and Ibuprofen.
-Take cough expectorant like Mucinex.
-Chew a Vitamin C pellet daily.
-Do steam inhalations.
-Avoid spicy and chilled foods.
-Sip on warm water throughout the day.
-Do warm compresses over the chest.
Hopefully, the symptoms will resolve within a week and if it worsens consult a General Physician and get evaluated.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Honey Arora, Dentist
