Hi., sir., From your given history,everything points towards allergic rhinitis.. Typically allergic rhinitis would present with watery discharge which is clear and sneezes which are multiple and it usually makes your nostrils tender and makes breathing uncomfortable due to the sore feeling in the nostrils. Basically what i mean is if you feel you need to do two things: 1-find the allergen(could be dust mites,pollen,aerosols such a deodorants room freshener etc,strong odors and so on) There are tests which can tell you which allergen you are allergic to but much simpler way is to maintain a log book for a month,and you can review the same to figure out. 2-I see that you are diabetic,so by default diabetics are commonly more susceptible to respiratory viruses,these are self relapsing but then a episode can give u flu like symptoms too,so to maintain proper hygiene is ideal.I would recommend you to stay away from unhygienic water and places. All said and done,you are advised to prevent an episode by the above methods,and in case of a episode best combination would be montelukast and levocetrizine tablets twice daily if its bad(optimally once before bedtime) and with steam inhalation(should not be very hot as too hot can also cause irritation to the nasal mucosa) Last but not least,the diet-avoid poultry and stored yogurt.Every day morning have luke warm water with a half lemon and honey. Hope this solves for any doubts please feel free to contact me.
