I can't simply wish the OP luck and health. I would however insist they seek some medical attention, at the very least. I'd hope they have, at this point.
My doctor isn't an ear specialist, but I'm pretty sure he could figure something out in regards to this lump in my earlobe. Or refer me to someone who would know something. (I really should get this seen, but I'm actively being dumb about it...) It seems to make sense that if you have concerns about the relations of vaping to your health, you would seek out a medical profession who knew something about your concerns. Not EVERYTHING, note. Obviously the research hasn't been completed to satisfaction.
The internet is NOT your doctor, by the way... (sorry, kind of unrelated, but it bugs me, haha)
Like some repliers here, I too felt a bit offput by the OP's extremely insistent claim that vaping DEFINITIVELY caused his symptoms. A claim unfounded by any professional diagnoses.
Let me share my little story about self-diagnosis. I've been hospitalized a few times since I started smoking. Asthma related complications. Once I was diagnosed with bronchitis, given medication and sent on my way. The next time, experiencing the exact same symptoms, I hobbled into the after-hours ER, claimed I had bronchitis and just needed the meds, please. Turned out there was no infections, and I'd actually been seriously overtaxing my lungs with smoke and overusing my prescription inhaler to the point that my body no longer reacted to it. Spent 4 hours breathing in cocktails of stuff just to get my lungs in a reasonably functioning situation again.
I may have thought I knew what was going on with MY OWN BODY, according to MY OWN EXPERIENCES, but I was still dead wrong. Doctor looked at me and told me I'd be killing myself pretty soon if I kept this up.
As far as OTC inhaler, and Primatine Mist... You want to know about some nasty stuff to be inhaling? Well this is it. I'm unfortunately stuck on the PM since my shady insurance dropped my coverage, and I can't afford a full price prescription. I've been on it so long that it doesn't seem like a big deal anymore, but I've also been lucky in that I haven't had any episodes where I really feel the need to overdo its use.
I do remember how it was when I first started using it, though. PM is strong, doesn't need as much to be effective, and lasts longer than a 'scrip inhaler, as a result. But it's incredibly harsh, too. It was burning my throat, as a smoker, even though I kept myself to the 4 hour dosing schedule. It has pretty severe warnings against using it too often, too many times in a day, and for too long of an extended period. In fact, following dosage directions, you wouldn't even finish the inhaler within the recommended directions. It's bad stuff, and though my body is now accustomed to it (a scary thought, I know), I'd be more likely to assume the OP's symptoms are related to the inhalers than the vaping. Assume, because I'm no doctor, by any means.
And 4 inhalers a year? Sounds like a big deal to someone who's not currently relying on them. Seems like nothing to me, who's been living on them for the last 10 years. If I were able to afford all my meds, even with insurance, I'd have a "rescue" inhaler (the standard puffer types), and a 2x daily inhaled med to keep me off the inhaler. I'd consider a SERIOUS case of breathing problems to be the one I CAN'T puff away. The one that takes me to the hospital. I'm a little stubborn about doctors, though. Haha.
If, once I start vaping, I experienced some minor symptoms, I definitely come to this forum as a database of knowledgeable experience and ask about some likely REMEDIES to those symptoms.
If I were have supposedly SERIOUS symptoms, I'd remember that the internet is not my doctor, and can not physically diagnose my issues. I would then see my real professional doctor.
I can't even understand what would drive the OP to come and post self-diagnosed claims, then defensively refuse any advice that would allow the vaping community to be able to refute the claims (and help the OP's personal health) or accept and integrate newly proven symptoms.
