Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice. I have gone through your query and can understand your concerns. It seems that you are suffering from allergic reaction as you have pets and yes, they can be a cause of allergy. It can be due to other causes like animal danders, pollen, certain trees and grasses and can also be any food or medicine. I would suggest you to consult an Allergist and get allergic tests like Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly. The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avoid exposure to it to prevent allergy attack. You can be advised to take anti allergics like Benadryl along with steroid shot to relieve the symptoms. You can also be instilled an Immunotherapy that will help in reducing the severity and frequency of allergic attack. Once the allergen is ruled out avoiding exposure to it can prevent the allergy symptoms. Hope I have answered your query. Let me know if I can assist you further.
