I have met doctors and diagnosed with slightly higher allergic count but not high enough to put me on medication anad have been advised natural methods like running, breathing exercises, high-fibre fruits like oranges, lemon etc. Though I am not able to start exercise regularly but still I dont know why I am catching cold on slight change in weather and temperature variances.
