One side of face feels numb on & off.

I often get a feeling of numbness in small parts of face ( corner of lip, cheeks, bottom lip & so on) it goes away after sometime but causes a lot of anxiety & I can feel the area just feels numb I guess …. I screened myself for a stroke and obviously not having one if I’m alert typing this. These symptoms have been occurring on & off for a few months, just don’t understand it. I just get told it’s all anxiety?? Help.
