i highly recomend you ,good hand massage instead of those way ,
old and traditional way of massage from good toucy hand always good ,obviously know kinesiology and anotomy ,cardio expert will do great massage ,
really important idea of massage , pressure, movement and positioning
stone and lava wont provide those ideas, I can recommend good hand in Covent Garden who can provide mixture of massage .
