New numbness. Getting a bit scared.

I have a doctor’s appointment on the 9th but im not sure i can wait that long. The past two weeks have been uncomfortable but manageable. Mind fog, sinus pressure, and my left arm and cheek lacking a bit of sensation. Yesterday most of the symptoms vanished except the numbness. And today when i woke up, i couldnt feel my right cheek either. As Im typing this im losing feeling in my left foot. This shit is frightening idk what to do. Feel like im having a panic attack rn. Anything that can help relieve this?
