I Always Have Allergy Nose, Eyes Itching Sneezing And Then

I always have allergy nose, eyes itching sneezing and then rash all over my body. I use to have this 5-6 times a year for the last 2yrs n have consulted skin n done lots of test and have also consulted Ent specialist they said nothing to worry about it not curable but will occur frequently so would like to know if this is so.
