Take Your own hand,make out of it a well trotted in fist(no empty places inside),now apply it (the fist)to an area You wish to massage.But no massage,just put the fist to the spot and press it in as far as Your muscle power allowes.No anything else-just hold the fist still in the spot,the deeper-the better.When tired,stop,going normal position.I use the method.Its simple,not tiring,safe, easily repeatable,very productive.But-no pain is ever to appear,if it does-stop NOW!Good luck.If hearing of such other methods,please inform me of them.Healingmethods are my interest
