I having extreme pain in my throat.

Some days back I had a kind of allergy insiide my mouth, it was very itchy. I used to have sneezing frequently. I got cold somehow and my throat started paining. I went to a doctor who diagnosed tonsils and and some swollen glands. After having the prescribed medicines I was good. I also had cold drinks in a marriage after it was cured. But from past few days the tonsils have started paining again. I took a antibiotic azithromycin course for six days 1 day each. Its the fourth day running I am still having extreme pain. I have avoided cold water cold drinks everything. I am also doing gargel twice a day. But the main problem is that I have to stay in A.C during my office hours. I think the A.C is making it worse. Please suggest me what should I do? Should I visit the doctor again or will it be cured If continue my medicines and gargel? Thanks a ton in advance!
