Hi Praveen,
In the first place I would want to know what made you to do gargles, i.e. what were your presenting symptoms. from your narrative you seems to have got too much panicked. Just be calm. Are you having sore throat or throat pain? Do you have loss of taste sensation/burning sensation on tongue? I'll require additional inputs to come to the diagnosis of your problem so that proper treatment can be provided.
Please consider for online consultation.
