numb face

Hi all

I had ON around 8 weeks ago. Just waiting for my MRI results at the moment. For around 4 years I’ve had numbness in the left side of my face. It used to come and go (there for a day/week or two) but now its numb all the time pretty much. But the sensation I feel does vary. Sometimes it feels like I’ve been to the dentist but some times it feels dead numb and like a weight is on my face. Over the last few months its extended to the inside of my mouth and tongue. Has anyone else experienced anything similar this?
