In every spring/summer i feel i am short of breath as if my nose is blocked. I have a dry nose. i feel suffocated at times when i think about it. I am a little clostrophobic so the very thought of travelling by air makes me feel suffocated. I am confused what is the problem. Is it all in my mind that makes me feel so as if i dont think about it much i dont even realize that i am having any such problem.
