Take the medicines as mentioned in the answer.

Detailed Answer:
Hi,thank you for posting your query on health care magic.

I can understand your concern.

You have taken tablet Zithromax(Azithromycin-it is an antibiotic) for 4 days but no relief.
You have started with another antibiotic-An Amoxicillin combination antibiotic-625 mg(mostly it would be Amoxicillin with clavulanic acid combination-625 mg) and Vitamin C.

Continue with Amoxicillin-Clavulanic acid -625 mg two times a day and Vitamin C.

Along with the above medicines, you should also take Analgesic and Anti-infammatory medicine like Diclofenac with Serratiopeptidase,
Antacid like Rantac and Betadine gargles.

A single ,low dose of Steroid like Betamethasone(1 mg) might help to reduce pain and inflammation.You may take it after consulting a physician.

Also do warm saline gargles.Drink plenty of fluids (warm).Avoid cold,spicy and oily food.

If your symptoms don't improve after taking above measurs after 2-3 days,then it would be advisable to consult an Otolaryngologist doctor.

Hope this answers your question.I would be happy to answer if you have any follow up questions.Get well soon.

Hi,thank you for making clear that which medicines you took.

I was not knowing that you also took tablet Ibuprofen .

If you are suffering from severe pain,you can take Oral steroid in the following dose(if you are not suffering from diseases like Hypertension, Diabetes,etc):

Tablet Prednisone 10 mg two times a day for 1st day,then taper to 5 mg two a day on 2nd day,and then 5 mg only once on 3rd day.

or tablet Betamethasone (0.5mg) three times a day on first day,then two times a day on 2nd day,and once a day on 3rd day.

You can also take Anti-inflammatory medicine containing Serratiopeptidase .

You will need to consult a Otolaryngologist for examination of your throat as you are suffering from severe tonsillitis and prescription of above medicine.
