just wanted to jump in here after experiencing one of THE most painful mouth ulcers of my life! few days before christmas, started feeling like a sore throat was coming on...2 days later, throat felt like i was swallowing razor blades. didnt feel ill otherwise though, so wondered how in the heck i could have came down with strep but not have swollen glands and/or feel like crap all over. finally got a flashlight out and took a looksee into my throat, and lo and behold there is a nasty ulcer right at the back of my mouth where my mouth meets my throat at the roof. ouch! this one little ulcer was making my whole throat SCREAM!
have been steady vaping @ around 18-24 mg for 2 months+ mostly pg, some vg, hadn't changed any of my other habits, EXCEPT i got some DIY stuff in trade from another member, and had made 4 bottles of liquid with the products sent to me the same week this Ulcer invaded my life. one of them was 50 mg Nic in a PG base, some VG for mixing, and several flavors... mixed up some cinnamon (think big red gum) mint choco chip with MCC flavoring and creme de menthe, and some Rasberry, using Rasberry flavoring (don't have the brand in front of me) only really preferred the Rasberry, so vaped on it for 2 days all day, then BAM, here somes this nasty ulcer. the ONLY one i have experienced since I started vaping, and since stopping that juice and gargling some salt water, i am happy to report it is gone as quickly as it came Thank DOG.
Dunno if it is related to the flavoring i used or not, but I for one am not taking a chance on that occuring again if i can help it. Rasberry is in the trash!
(my good friend heavily vaped on the Cinnamon for several days with no ill effects, so I am not considering the other parts of the mix to be a contributing factor at this point, just the flavoring i used in the Rasberry, as far as i can tell....)
JMO on this subject, just happened upon this thread when looking for other instances of similar side effects of flavorings.
