Thanks for query,
You should find out the cause of allergy
You observe that after any particular type of food you get urticaria
,avoid that food.By trial and error you will find out which food gives you urticaria.
Certain pollen body can produce this complain.
If you have warm infestation,it may give you urticaria.
Go for stool test
for ova and cyst
Take less salt,sour thing.
ok and bye.
