He never mentioned pain, only a burning sensation.
Pete, the work I do is structural bodywork, simliar to Rolfing or myofascial release (which are different things, but as far as I understand going for the same ultimate goal).
Fascia has the property of thixotrophy (sp?) which means that with heat and friction it gets softer and "melts" which means that using these bodywork techniques you can change the structure of the body. When doing this type of work, clients sometimes report a burning sensation.
I won't go into the whole technique/system here, but you can look into further research or continuing ed if it interests you. There are plenty of posts here on the board about these types of work: corrective work, orthopedic massage, connective tissue massage, deep tissue, rolfing, hellerwork, structural integration, etc etc. All different or varying techniques on the same basic theme. Slow, deep, almost-static-but-not-quite bodywork with little to no lubricant
