Welcome in H.C.M.
Your clinical history is clearly indicating that your severe sore throat
with burning is appears to be because of nicotine
gum. Here I would like to suggest you -
1- Avoid this gum in future.
2- Take dispersible Deflazacort
to get immidiate relief.
with anaesthetic like Mucaine gel may be helpful.
4- Local application of boroglycerine is also useful.
I hope this will help you.
