So I smoked cigarettes for 18 years, started vaping for 6 months, went back to analogs, and now vaping again. I prefer mouth to lung, however I bought a mod and subtank so I was straight lung inhaling for a while. It wasn't satisfying me so I went back to my Nautilus using 12mg juice. For the last few weeks I've been getting strange feelings in my throat, chest, and back. The back is the worst. After vaping I would get these dull aches in my upper back right side that would travel to my side by my ribs, then to lower back. Sometimes it feels like a sharp burning sensation, sometimes a dull ache. It's really starting to scare me because I never felt anything like this in my 18 years of smoking cigarettes. Sometimes a mild throbbing pain in my throat and chest as well. Something is telling me that this "vaping" frenzy ain't all it's cracked out to be. I'm going to quit vaping all together. I read on the forum while searching for similar experiences that this guy ended up getting thyroid cancer from vaping. Has anybody here experienced these strange tingly dull ache's and burning sensations in their back? I've also noticed a slight pain on a full inhale but that's very rare. If vaping is so much healthier than smoking, then how come I never had anything like this when smoking my whole life? .... vaping, I'm done with this crap... My lungs feel heavy, achey, and I'm getting strange dull pains. I'm going to quit and see if this gets better. Sucks because I really loved it, maybe I over did it...
