Since I was young, my parents have always taught me that I should always drink warm water whenever I'm not feeling well (i.e. cough, flu, etc.). Recently I got a terrible gum ulcer and it sure hurt bad!

I faithfully consumed warm water far almost a week and there was no improvement at all, if not worst. After this I started to drink cold water. The ulcer was gone in two days...

I am not a doctor, so I'm not sure how well this works. Give it a shot!
