### input:
I have post nasal drip and sores on the side of my tongue. I drink a lot of fluids, but I feel like I have to keep sticking my tongue out to swallow properly and I feel as though I have to swallow constantly. I have been experiencing allergies and taking Allegra and a nose spray for the past 3-4 weeks-I thought maybe they were the cause of the discomfort of having to keep my tongue out. However, since I stopped both medications, the symptoms remain.

Cellophane You for contacting Chat Doctor. As you have chronic allergy problem, so I would recommend you to try following:> Avoid dust as it plays a major role in triggering allergy.> Use levocetirizine one at night for 5 days for allergy.> Take montelukast once daily for one month. Research has shown that it reduces allergic response.> Take hot water in a cup, add 1 tablespoon salt in it. Perform gargles (mouth wash) with it three times a day for at least 3 days.> use lidocaine gel on sores in mouth. Apply gel on sores for 1-2 mins, then mouth wash with plain water(Do not swallow it)It will start resolving by itself in 2-3 days. I would also suggest you to undergo allergy testing at allergy clinic as you have chronic allergy problem. It will tell that you are allergic to what specific thing. The results will help an allergist to prescribe you immunotherapy to that specific allergen, and it will improve the problem.AVOID:> Chat Doctor.
