Hello. 2 months ago I had cold flu and was coughing a lot. The cold flu was gone but I am still coughing (not a lot - maybe 2 times a day but for 1 minute). Yesterday I when I coughed I felt a pain somewhere between middle and left side of the chest. When I am taking a very deep breath I sometimes feel this little pain but sometimes I don't. Also, I feel this pain sometimes when standing up from a chair and when coughing. I will go to check this at the doctor but I am very afraid of having something like lung cancer? I have been smoking 4 months now but only 4-5 cigarettes a day. I decided to stop smoking and I am going to. I really regret starting it. Is it anything serious? 
ps: I also lift weights and the day I got this pain, I lifted more weight than I am used to, so it may be something with the muscle.
Note that I don't feel this pain every time I take a deep breath or standing up or coughing but some times.
I'm very terrified :S
