olfactory hallucinations and nerves tingling

I've been seen by few doctors and they think I am crazy after telling them what has been going on with me.

For the past 6 months, I noticed whenever I touch my face next to my nose (around the cheeks), I could feel tingling around my upper lip. It is disturbing. There isn't any dental issues.. I went to a dentist few times already and they did not see anything wrong with my teeth. I did have a root canal 5 years ago but no problems with it since.

Now when I came back from a trip in February, I started smelling smoke. There is no one around me that is smoking. I have asked people around me in the house and outside making sure there isn't any smoke. I find it weird when the tingling is gone from my face when I touch, I smell smoke. When the smell is gone, the tingling is back. Right now, I can feel the tingling and smell the smoke at the same time.

I have an appointment with an ENT on Tuesday and back to my neurologist next week. I had a brain MRI few weeks ago and everything was clear. I had blood work and all was normal.

I've tried to find information what could possibly cause this. I just really hope the doctors will find something because this is just really disturbing to me. I am 31 years old female.
