Anyone experienced any type of back pain after quitting smoking OR when the started vaping? It has been 3 days since I started vaping which was also the last time I have had an analog stick as well. While I am very proud of myself for going 72 hours without a cig I noticed yesterday that I had a small pain in my upper right side of my back below the shoulder blade. I am wondering if this is some type of withdrawal symptom or if possibly I am vaping incorrectly and pulled a muscle or maybe when I was coughing up phlegm or if this is all just a coincidence and I did it sleeping funny or something. If it gets worse I would obviously take a trip to the doctor but if this is something others have gone through I can ease my mind a little bit knowing this is just another downfall of smoking for so many years.
