Hi Dr. Aashish Raghu,
Thanks a lot for your prompt reply.
As you mentioned, smoke, dust, any kind of foul smell, cold
weather is bothering me most (from last few months). I went to one of the prominent hospitals of Bangalore and after two weeks medication they are advising Nasal surgery, saying my nasal cartilage
moved left, but once i am am away from Bangalore, my blocking nose is no more. And yes, brisk walking helps me a lot i realized.
Your prompt reply is highly appreciated. Once again, thanks a ton for your great suggestions.
