I have nasal blockage, sneezing (25 times a day), itching in my nose, and can't sleep. Ortivin hasn't helped and made it worse. My mouth is dry, and previous treatments with RID AR and Allegra M are no longer effective.
It sounds like you have severe allergic rhinitis that is not responding to your current medicines. Dry mouth and worsening symptoms may occur with some nasal sprays or antihistamines. You should see an ENT specialist or allergist for a proper review; they may recommend a stronger or different nasal steroid spray, antihistamines, or allergy testing to find triggers. In the meantime, try saline nasal rinses, keeping your environment dust-free, and using a humidifier to ease congestion and itching.
