I am due to have a transnasaloesophagoscopy tomorrow during which they use a lidocaine spray to numb the throat and larynx. I know that when I go to the dentist I cannot have the lidocaine injections as it sets of my palpitations.
Does anyone know whether a lidocaine spray in the throat would have the same effect and if so what would be used as an alternative? I'm panicking more about that than the procedure itself.
Thanks in advance.
