Hello, Sorry to hear about the uncomfortable experience with the physician. Well, I think you need to provide some more details, as this has been from over a year, I would like to first ask this, have you underwent any dental procedure?? As while providing anesthesia, there might be small damage to the nerve and gets unnoticed by most.  Next, if not the above one then have you been suffering from pain or anything like that? Because this is related to the cranial nerve and pathology of the same.  We need to do some cranial nerve testing and then figure out what exactly it is and why the issue is. I would recommend you to undergo some cranial nerve tests, you can find this online too. It's a basic test and nothing difficult to perform, but it will be good is any neurologist or physiotherapist performs the same. To get better accuracy. Once we figure out which nerve is involved and the entire history of you about the dental procedures that we can plan the treatment. In my clinical practice of 12 years, most patients get ignored post dental procedures and have cranial nerve issues. But timely assessed and examined the treatment begins, and they are better with. Please note, I am not claiming that dental procedures have done damage with purpose, but the human body can act in any direction without prior notice. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
