I don't know if its been mentioned already but it sounds sorta like an allergy to metal especialy with the sores around the mouth. You might want to check into that. Good luck and I'm so sorry for your situation.
I would have to vape at a very high rate.
I'm one of those... I have rheumatoid arthritis (a very nasty case of it - it's been attacking the sheath that surrounds the nerves in addition to the usual joint stuff). It's only been 4 months, and while an immune suppression effect would be nice, I'm not seeing it.Some here have Auto-Immune disorders where the immune system constantly attacks the body. Be nice if vaping did suppress it, but doesn't seems to- at least for some.
