About a month ago I experienced what I thought was a muscle spasm in my upper left temple. I could actually feel the veins moving when I placed my hand to my temple. Eventually it stopped. A week ago I started to experience tingling in my legs, the left more so than the right. I have also felt some involuntary muscle jerks. On yesterday, I had this pressure to start on the left side of my face and move over my entire face. It lasted for a while, then went away. Today, I've felt the same sensation. Then it feels like my nerves are twitching internally, as I can't see any movement in my face. Is this something I need to have immediately checked out? Can you help?
