Hello,
Thank you for posting your query at DoctorSpring.com
I can understand your problem.
You are suffering from throat pain, difficulty in swallowing and fever for 5 days, You had white and yellowish patch on posterior part of thorat. All this confirms that you are suffering from acute tonsillitis. You have completed course of azithromycin and now on amoxicillin.
Amoxicillin in first line drug for acute tonsillitis so you can continue same for a total of 7 days so you can continue for another 4 days.
You can add following medication-
Levocetrizine 5mg one daily for 5 days (antihistamine medicine help in reduction of congestion)
Aceclofenac (Zerodol) 100 mg two times daily for 3 days (will reduce inflammation and pain)
Rabeprazole 20 mg once in morning for 5 days (will prevent gastritis)

If you want a throat swab for culture sensitivity for causative bacteria, itcan be done, but it will be negative only now as you are on antibiotic already.
You can do saline or betadine gargle two times daily.

Hope this helps
Best Regards
