Cough, dryness, unclear nose.

I am not sure how much is related a common problem I have. The primary problem is I get a significant amount of mucus/cough when I ate a lot foods, and no not just dairy, but a lot of other foods that do not contain dairy. I have gone several days with out dairy products and still get mucus build up from eating. I also don't feel like I can breathe well through my nose. It doesn't feel congested like when you have a cold but it does feel like I can't get enough air when I breathe. As a result I think I sleep with my mouth open. I have been prescribed an alternative of FLUTICASONE. Which improved it slightly but I don't think works as well, althought I'm not as sure.
Onto my current more irritating issue.
I have had a cough for at least a week or more where it feels like there's maybe a tiny buit of mucus, but nothing really comes up. I am still taking my FLUTICASONE and have also tried mucinex D, dayquil, sinex, and cough drops. Now i feel thirst/ dry Throat, and some slight throat pain, accompanied with a feeling like there are a few bits of stuff in my mouth/throat when I cough. My physician is booked for several weeks.

Hello and hope you are doing well.

Repeated episodes of dry cough, runny nose and throat irritation could most probably be due to allergens. These are substances like pollen, dust, animal dander, certain foods, insect venoms and certain medications. Exposure to allergens causes a runny nose with a resultant post nasal drip where secretions from the nose go backward into the throat and irritate causing cough. Cough is a protective mechanism by the body as it helps to prevent infections. You will need to consult your primary care physician for proper clinical assessment. In the meantime for relief from your symptoms you could do warm salt gargles and take OTC antihistamines.

Hope this helped and do keep us posted.
