I have been smoking since a year now, my frequency of smoking used to be like twice or max thrice a week . Since last month i had almost started smoking daily, 1-2 a day. Last week I had pain in my chest aligned to the centre and left and my throat was burning. Immediately I stopped smoking and now its a week but I still feel the pain when I wake up in the morning. It seems to be coming from within the ribs. I feel the pain sometimes in the day. Can you please advise me is this actually because of smoking or any other reason could be behind it. I did not lift any kind of heavy stuff also.
