The symptoms can also be due to cat allergy
. Since you have known allergies to pollen, dust mites and
pet dander, chances of cat allergy
are high. You may have always been allergic but symptoms may not have been very pronounced. Only a skin test (that tests for cat allergy) will rule out for sure whether it is cat allergy or not. If it is cat allergy, then if you do not take anti-allergic pills, the symptoms will resurface time and again.
