Hi! your symptoms of running nose and cold with variable fever and related to winter season without any other symptoms like dyspnoea, wheezing or expectoration of cough points toward allergic rhinitis
or common cold
To rule out deviated nasal septum
and chronic congestion of paranasal sinuses you should go for caldwell view and water's view X ray and CT scan of para nasal sinuses and consult an ENT specialict with the report if any abnormality detected.
For the prevention of allergic rhinitis first of all go for detection of the possible allergens by panel test for allergy, then its better to avoid exposure to these agents.Avoid carpets, woolen clothing, keep windows closed, keep house dust free, avoid fur pets like cats and dogs.
If acute attack present then you may take levocetrizine 5 mg O.D., sodium chromoglycate nasal drop few drop twice a day, topical nasal steroid betnesol N. for fever paracetamol
500mg SOS. Sinarest tab 25 mg B.D. ,steam inhalation with tincture benzoin, vitamin c tab 500mg BD, doxycycline 100 mg BD on first day then OD for five days.
wish you well. thanks
