Numb sensation on face, usually when chewing.

For the past 3 days, at random times, mostly when I am eating/chewing, a tingling numb sensation happens in my left side above my cheekbone / temple area. I don’t have a headache, it’s just this sensation randomly throughout the day, comes and goes within 5 - 10 seconds. Any clue what this could be, and if I should go to the doctor?? I don’t have insurance so I only go if I really have to. I also have a cough/mucus and am currently getting over a cold, not sure if this could be related.
