I am a smoker I take bong hits frequently and for over 3 months I have been experiencing a long lasting pain in the right side of my chest to my right armpit and upper right arm, (only underneath). It is not an intense pain it’s a heavy but sensitive sensation that makes sitting still uncomfortable. Once the pain starts it will usually stay for an hour or so and then fade. Also I find twisting my body to the left relieves it a bit as does stretching my right arm out but only temporarily
