Hi, My name is Bryson and I am 25 years old. I have been smoking regularly for around 8 years. I also run a furniture company where I am exposed to dust particles from mainly wood species. For the past 3-5 months I have been getting a sharp needle like pain under my left breast at random times and usually last at full intensity for 5-10 minutes and then a very dull uncomfortable feeling for a following 5-10 minutes. Sometimes I have taken in a very deep breath and almost felt like a pop and the pain has gone away. Just looking for some thoughts
