I have experienced a sudden loss of grip in my left hand, plus numbness in 3 fingers and cheek / left jaw, pain in the left side of the head. Today is the third time that has happened this week, it usually last 5 to 20 minutes each time. What is this?
I think with such dramatic changes and sudden loss of motor function and sensation and headache, you should call your doctor immediately to ask if you need to go to the ER. He's young, but its symptoms can be warning him of an impending stroke or something similar. Please call your doctor now.
