Find a foot-long piece of wood. The radius of this log must be the same as the length of your ring finger. Saw it from the middle and made it into two semicircular "pillows". Put it around your neck when you sleep, and then put something on the occipital bone slightly, not too high, so that the neck pillow can be lifted to a comfortable angle on the wood. Oh, by the way, remember to put a thick towel on the wood, otherwise it will be too cold.
This method originated from the ancient Japanese regimen. I won't get used to it at first, but I'll get better gradually. Always keep your neck warm, sleep on a hard bed and maintain your spine. I wish you a speedy recovery! ~
