hi there, as you have noticed that smoking
is making your throat worst and it is not a co-incidence. The toxic fumes of the cigeratte is causing irritation of the throat whhich is manifesting as pain and irrritation. You will need to cut down or totally stop smoking as not only now but in the future also it can be harmful to you. You may do warm saline gargles and use cough
drops to decrease the throat irritation
. You may also use ansti-inflammaatory tablets after meals to decrease the pain. Permanent cure would be to discontinue smoking. Take care.
