Hi I am 21 years old . I have started smoking a year back and I was smoking nearly five times a week . From past one week , I am experiencing pain in some portion of my left lung(towards the center ) mostly immediately after I smoke and even somtimes in between also I experiece the pain(not so svere) . I am bit afraid of going for a lungs checkup :( Can someone please tell me Is it due to smoking and how harmful is it .
