Brief Answer:
may be due to sore throat which causes swollen glands.

Detailed Answer:
Hello,

I have gone through your query and here is my advice.

As per your history, actually sore throat or sinus infections can cause bitter taste in mouth. Such infections can cause swollen glands.

Please let me know do you have fever, swallowing difficulty, cold, cough with yellow or green phlegm?

For that you can take tab. azithromycin 500 mg once a day. In case of fever you can take tab. acetaminophen 500 mg three times a day. These medications should be available over the counter.

Along with that do saline or betadine gargles and take steam inhalation two times a day. Keep yourself hydrated.

Let me know I can assist you further.

Regards,
Dr. Shyam Kale
