Qansa..Walaal, you are simply allergic to something...The important question is "What is the thing that you are allergic"?
As the saying goes.."To know the decease is half of the cure"
So it depends what you are allergic to? I understand that you said seasonal allergy which means you are probably allergic to Pollen Grains...Some Cities are worse than others...
I am also allergic to pollen, but mine is not severe, I feel like my eyes are itchy sometimes...I think I took Penedryl for three times only in my life, but I try to avoid touching the pollens that are covered in my car etc even though they are in the air! I just like to avoid medications..
So it is your choice walaal and it depends how severe is your allergy..If it is severe take the medication for allergy not the medication for Germs and stuff like Garlic won't help..It is like you are taking antibiotics for allergy and you know it does not work...
