This sounds like Eustachian tube dysfunction, where the passage connecting your nose and ears swells, likely triggered by your dust allergy. While Vicks provides temporary relief by opening nasal passages, it does not resolve the underlying congestion. To help, try using a generic saline nasal spray regularly, applying warm compresses, or practicing gentle swallowing exercises. I recommend discussing generic nasal steroid sprays with your doctor, or checking for jaw-joint issues, since the sound is linked to chewing.

While Vicks can offer temporary comfort, it only masks the smell rather than treating the underlying cause. Please don't worry, as these conditions are very common and highly treatable. I gently recommend seeing a primary care doctor or an ENT specialist to examine your sinuses, and checking in with your dentist. Staying well-hydrated and using a simple saline nasal rinse might also help soothe your nasal passages in the meantime.

Yes, applying Vicks inside your nostrils can contribute to this. Petrolatum-based products can easily block the delicate oil glands or hair follicles inside your nose, potentially leading to localized inflammation, a clogged gland, or a minor infection. Additionally, putting these ointments inside the nose is not recommended because inhaling the ingredients can affect your lungs. Since the swelling has lasted for almost a month, please have a healthcare professional examine it to ensure it heals properly.

I am so sorry you have been dealing with this persistent dry cough for over two weeks; I know how exhausting that can be. While diphenhydramine (Benadryl) and Vicks can offer temporary comfort, they are not addressing the root cause. Since your cough has lasted more than 15 days, your best next step is to see a doctor for a proper evaluation. They can check for common causes like post-nasal drip, allergies, or acid reflux, and prescribe targeted treatments. In the meantime, try staying well-hydrated with warm fluids and using a humidifier to soothe your airways. Please take care.

It is generally safe to use a Vicks inhaler for temporary cold relief, but please limit its use to 3 to 5 days. It is restricted or banned in some countries because certain formulations contain levmetamfetamine, a decongestant chemically related to stimulants, which triggers strict local import laws. Overusing the inhaler can irritate your delicate nasal lining and cause 'rebound congestion,' which might feel like worsening sinus pressure. Used sparingly, it is very unlikely to cause sinus problems.

Please be reassured that a white blood cell count of 11,200 cells/mcL is only slightly elevated. This mild increase, combined with persistent sneezing, is most commonly caused by a standard viral infection (like a cold) or allergic rhinitis, as your body fights off a virus or reacts to environmental triggers. To help calm your sneezing immediately, I recommend using a sterile saline nasal spray to flush out irritants and staying well-hydrated. An over-the-counter generic antihistamine like cetirizine can also provide quick relief. Please rest, and consider consulting a healthcare professional if your symptoms persist or worsen.
