Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern...
As per your complain the itchy spots over the palate seems to me to be more commonly due to allergic reaction to either any food or medicine[if you take] or any allergen present in air like dust,pollen,animal danders etc..
It does not seems to be due to constituents of liquid cigarette as yo are already taking it from 9 months but can be a
delayed allergic reaction so it cannot be removed as the cause..
Nothing to worry, as of now you can take
Cetrizine or fexonfenadine [allegra] which are antiallergic medicines and can provide relief from itching.
Gargle with warm saline water.
gargle with 1:1 solution of
benadryl and
milk of magnesia will also help..
Avoid smoking for sometime.
In case if there is improvement, then you can consult a physician and get evaluated and get a
blood test done for allergic testing and it will help in ruling out the exact allergen so that you can prevent exposure from it..
Hope this information helps..
Thanks and regards..
