Rhinitis has a runny nose as long as the weather is cold.

According to your description, it should be allergic rhinitis; Allergic rhinitis, also called allergic rhinitis, is a common and frequently-occurring disease, which can be divided into perennial allergic rhinitis and seasonal allergic rhinitis (also called pollen rhinitis). It is an allergic disease of nasal mucosa, which can cause many complications. Allergic rhinitis can be complicated with allergic conjunctivitis. Pollen is a respiratory allergic disease mainly caused by pollen. The main clinical manifestations are nasal itching, continuous sneezing, a large number of clear-water nasal mucus, nasal congestion and so on. Some patients may also have itchy eyes, tears, conjunctival congestion and asthma. Not all plant pollen can cause hay fever, which mainly depends on the antigenicity of pollen. For your health, it's best to go to a standardized otolaryngology department for detailed examination and make a clear diagnosis before treatment; Conservative treatment can take oral antiallergic drugs (such as chlorpheniramine tablets, loratadine, cetirizine capsules, ketotifen capsules, etc. ), as well as topical Berkner spray, Raynaud, flixonase, Ubisoft spray, etc. You can also take the following treatment methods: 1: cold compress the nasal cavity with a cold towel; 2. Wash the nasal cavity with normal saline; 3. Eat more fresh vegetables and fruits, eat more foods rich in crude fiber and water, and avoid smoking. 4. Correct bad habits such as picking your nose casually. 5. Wash your nose three times a day with a nose washer (plus normal saline). This method can increase the immune function of nasal mucosa and is a more suitable method. It is suggested that low-temperature plasma therapy should be used in surgical treatment, the main purpose of which is to reduce the volume of middle and lower turbinate mucosa, submucosa of nasal septum, nasal sensory nerve and parasympathetic nerve (anterior ethmoidal nerve), directly make some glands or some cells of glands in the treatment area coagulate and die, reduce the excitability of cholinergic nerves, thus reducing the secretion of glands, and also reduce the release of vasoactive peptides by destroying parasympathetic microganglions and SP nerve fibers in deep nasal mucosa, thus reducing vasodilation. I wish you a speedy recovery! ! !
