I have been suffering from throat infection for the past five years, every month I get throat infection, I use Azax 500mg three days to get rid of it. Can you let me know the reason behind the frequent throat pain. I'm tired of taking Azax every month. I feel very weak when I get the throat pain. I'm unable to find the reason for the infection. May be I'm allergic to some food, I stopped drinking anything that is cold since many years but that's not helping. Your advice would be of great help
