My tongue feels like i got burnt by a very hot drink. should i be worried?

It is temporary: Our tongue is prone to get affected by what we eat and drink. There are many viruses that can cause sores on the tongue. Most often our immune system heals these afflictions. If it is not better in 2-3 days take a short course of Vitamin-c, 500 mg, 1 tablets daily for one week. it is harmless yet, it may do you good as it improves the immune system.
