Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from upper respiratory tract infection, also known as Common Cold and the symptoms of nasal congestion, sneezing and runny nose are all due to cold.. Excess salivation is due to throat irritation with the infection leading to over stimulation of salivary glands leading to hypersalivation.. Also reduced efficiency of swallowing due to throat irritation is another cause for noticing saliva swallowing and a false feeling of excess salivation.. The infection will however resolve once the virus will complete its cycle in human body.. As of now you can start with supportive treatment to relieve the symptoms like: 1. Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to make a luke warm solution.. 2. Take a combination of decongestant like Phenylephrine, mucolytic like Ambroxol and anti allergic levocetrizine and another combination of Acetaminophen and Ibuprofen.. 3. Do steam inhalations.. 4. Avoid spicy and chilled foods.. 5. Sip on warm water throughout the day.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
