My last Thai massage before leaving Thailand was the night before I left. Travel back to the States was a daunting twenty hour endeavor including a three hour layover in Hong Kong. My instructor for a three day arm and hand massage training at the Loi Kroh Thai Massage School was Kom, and he was recommended as an excellent Thai practitioner. He has twenty years of Thai massage wisdom, and he was as fantastic as his reviews! In fact, I credit him with finally ‘fixing’ me. I’ve had hip challenges for a few years now, and my left hip and lower back felt as if they were slowing cementing into themselves.
Most movement had become tiring with all that pain. 
Kom used a modality new to me called Tok Sen. ‘Tok’ means ‘to hit’ and ‘Sen’ refers to the energy pathways (aka meridians) within the body. The wooden chisel and mallet used for Tok Sen produces penetrating vibrations that resonate through the deep layers of muscle, connective tissue and bones. These vibrations help soften stiff bodies and provide much needed pain relief. It is a rhythmic massage that is administered with a combination of three consecutive taps and continuous movement along the Sen lines to disperse energy. It was intense and it felt like the tension in my body was slowly being chiseled away, and indeed, it was! He worked me over for 2+ hours before he took out the mallet and wooden chisel and thank goodness! I have been home for about seven weeks now, and have been relatively pain-free since that awesome experience.
Bear in mind that the standard Thai massage appointment in Thailand traditionally lasts two hours! Every one of my Thai massage samplings was two hours or longer. I especially like that tradition!
