I do the myofascial release at home using a racket ball or a tennis ball. May take a while to find the trigger place in the muscle giving the pain. I will admit it smarts to keep the pressure on. I place two in a sock and use at the base of my skull. Speaking for myself it does hurts and one need take it slow (a tennis ball). Once that muscle releases you will know. Again, what works for me. Not a fan of massages, etc. A PT shared this with me and I have been thankful.
Worth a try-or not.
