Thanx ev1 for replying,
I stay in New Delhi, India. It is not humid in March.
I went to a subsidised government Hospital for xray and Check up.
The Docs there have many patients to take care of(India's huge population), so he checked me up quickly in about 2 min, then saw my Xray and said that nothing is wrong.
Gave a few Anti allergic medicines and told me to go home. I told him that i smoked ocassionally(8 cigs a day...sorry couldnt tell the truth).
I think i will wait for another 2-3 days.
I coughed out a bloody sputum today too
