(No mango's DC2...unfortunately the season is over. Winter here.

I just want to say that you guys are just SO kind! Thanks so much for trying to figure this out for me and for all your helpful suggestions, relating of your own experiences and pm's.
I've literally been sitting here bawling my eyes out because this is so disappointing to me and not an easy decision to make at all but I really AM miserable and in pain.
I doubt whether this could become something life threatening. Surely that would have happened by now? No breathing problems at all, but it is becoming rather sanity threatening.
Ok, so I have a plan!
I'm going to stop vaping today and go back to smokes. I know, I know....cringe....but I feel I have to so I can get back to what was normal for my body before I began vaping.
I have never chewed nic gum OR used the lozenges so I don't know if they will throw some untoward symptom into the mix that might confuse the issue.
I'll do this for a week or so and see if this rash goes away.
If it does go away then I'll start vaping again with a new brand of VG and no flavour whatsoever.
See how that goes.
If I get any untoward symptoms I can assume then that it's a VG intolerance.
SO....then I'll switch to PG and NO flavour.
By then surely I should know whether it's the VG.
After that I can start slowly introducing flavours - not that the flavours bother me that much to be honest because I can hardly taste them anyway - not with VG anyway.
So I'll do a slow process of elimination. It's all I can do.
I'm NOT going to give up the idea of vaping because I want more than ever to not smoke!
