Facial Pain from Lorazepam

I started to take lorazepam about 5 months ago regularly for panic disorder and OCD.

I started to get gum recession after starting this med and now i have constant gum and teeth pain and 24/7 tingling on my face. I am based in London UK. If anyone can recommend anyone to go see that would be great. I am now severity depressed because of this and my doc wants to give me more meds- on top of the two im already on.
