I am suffering from weird kind of disease, I know it's a kind of allergy, dust or pollen maybe. The symptoms are even weird nothing happens to me when I am in home or roaming during evening time. But if I go out in mid afternoon the condition is worse, getting dizzy and blockage in nose and ears. Also I can fell the same condition when I am in a place where air conditioning is less. I have many allergies in the past includes food allergy, but I didn't continue any treatment because it vanished as days passed. But this thing is happening now, I know it's allergy. Can I know what kind of allergy could it be. P.s I have undergone sinus surgery four years back.
