Every so often in the last year or so I would get this feeling in my mouth sort of like my tongue had a sour candy on it. Tingling feeling and hard to explain. Today I had that feeling on my tongue and I started fixating on it and now I cannot sleep as my mouth feels like it is hyper salivating and my tongue is so tingly it almost feels numb. I am a life long anxiety sufferer and this would be new to me for a symptom but curious if this even could be anxiety? On the other hand I had a physical in January and all my blood work and everything else looked normal so I don’t know. Appreciate any advise or input as I am really struggling
