dear doctor, i have mild chest pain from past 2 month. it feels most when i breath in, and becomes most at the end of breathing in. i also feel the pain while stretching muscles around the chest. on some days, i get high coughing and wheeze with some noise while respiring. i have a habit of smoking tobacco n weed (currently a max of 3 a day including both). i have been smoking tobaco for around 10 years and weed for 5 years. i am now much worried for this pain, what would you suggest and what do you think about this?

am sorry for my bad english, because am not a native speaker.
