The best treatment for this condition is resting your voice box. the more you try to shout, the more inflammed they are going to be. This can be achieved by warm saline gargles, aviding speech and using awriting board to communicated. NO SHOUTING Images available only to Customers.
Taking an anti-inflammatory maybe useful (MOTRIN), if you have some throat pain.
