Could occasional watery discharge be CSF with nasal polyps?

Concerns about an elongated uvula are understandable and can be caused by factors such as dehydration, allergies, or inflammation. Considering you are merely feeling a little weirdness while swallowing but breathing is okay, it may not be a life-threatening event. Saltwater gargling is the first step to getting relief. Alongside that, drinking water is just as important. When things get worse, or you face such a problem as shortness of breath, and increased pain, please consult an ENT specialist. 

You appear to be coping with nasal congestion and your nose is swollen due to allergies. A situation when your body reacts to things like pollen and dust may cause your nose to feel stuffy, while the inside of your nose may get swollen. This may block the airways, thus making it difficult to breathe. You can try saline nasal spray to clear your nose and avoid things that trigger your allergies. If it continues, you should visit an allergist who will assist you in finding a suitable treatment for your allergies.

Built-up ear plug can create an issue of a feeling of being uncomfortable, a reduction in one’s hearing ability, or the illusion of fullness in the ear. Mainly, it is the misuse of cleaning methods and anatomy of the jeopardized narrow ear canals. The other reason might be a skin disorder. To dissolve the wax that has become firm, try mineral oil- or saline solution-based, over-the-counter drops. To prevent earwax from being pushed deeper inside, do not use cotton swabs. If the healing process at home is ineffective or you are in pain when doing it, it is recommended to see a doctor.
