My good friend has had a numbness on the left-side of his head (above the ear all the way to the crown) for about a month now and he won't go to the doctor .
The numbness ranges from the top or crown of his head , to just above and then behind his left ear .
Is this a warning sign of stroke or heart attack ?
If not, then what could it be ?
Give me everything you can so Ii can convince him to see a doctor .
Thank you .
What Is TMJ ?
