Hi wll come to HCM.
It looks you are getting allergic throat infection
. To prevent this you got to wear mask
when you are out and in polluted area.All allergic people have allergy
ND polluted air in common.So this will help you to prevent allergy which is very common.
In addition avoid cold drinks, ice cream etc and if smoking
give up smoking.Garfging with
luke warm water will help you to minimise irritation in throat. In case of need you may use drug like cetrrzine for allegy or some cough linctus to smoothen your throat and
for fever. Thanks
