Thank you for the advice

I am due to have my yearly check up at the dentist next month anyway so I will still keep the appointment but I will book another doctors appointment next week and ask to be referred to an ENT.
I would never have thought that at 26 years old I'd be worrying about this! I have ordered one of those electronic cigarettes and I'm not buying anymore real cigarettes!
Thanks for telling me that it's not the base of my tongue, I really have no idea how long it's been there for.
