About 3 months ago I started to notice pain in my chest whenever I smoked as well as shortness of breath. Also I began to feel a tingling sensation in my shoulders and sometimes in my arms. I was smoking very heavily during this time and have since cut back a lot. I plan to start running 5 days a week, i think this will def help. For the most part I am done smoking, the pain is not worth it and I don''t want it to get worse. I am planning to get a vaporizer but was wondering if anyone has already tried vaporizing instead of smoking but has still had the chest pains afterword?
