Hello.
Thank you for asking at HCM.
I went through your history and would like to make suggestions for you as follows:
It is possible to have nose and
asthma symptoms due to
allergy to cat
proteins.
I would suggest you allergy testing for cat proteins. If it is positive, the best option in my opinion would be removal of cat from home.
If it is not possible to remove cat from home, preventing cat from entering bed room may be an alternative.
An Allergist-Immunologist may prescribe allergen specific
immunotherapy for cat which works on immunity to improve allergy symptoms on a long run.
Other important measures are washing cat at least weekly and minimizing carpets, curtains and upholstered furniture from home, especially bed room which are reservoirs of cat proteins.
Hope above suggestions will be helpful to you.
Should you have any other query, please feel free to ask at HCM.
Wish you the best of the health.
Thank you & Regards.
