while the bottom surface remains in stationary contact with the surface of the skin 12 if the tip 27 or bottom surface 35 are not circular then a width measurement and ratio can be used in place of the diameter measurement and ratio in one example the diameter of the tip 27 is approximately 0 5 inches and the diameter of the bottom surface 35 is approximately 3 inches in this example the area of the bottom surface is approximately 28 inches squared compared to the area of the tip 27 which is approximately 0 8 inches squared because the side wall 21 is flexible the tip 27 can laterally travel over the large area of the bottom surface 35 while the bottom surface is stationary on the skin 12 the bottom surface 35 is generally flexible too so that when the tip 27 is moved for example to the far right a portion of the bottom surface 35 on the left side will lift from the skin 12 slightly to permit the tip 27 to move to the right yet further when the user desires the pouch 34 can be lift or slid to a new location on the skin surface 12 fig1 c shows an alternate embodiment where a second reservoir 36 is provided by sealing a second ply of plastic to the bottom surface 35 of pouch 34 to provide a interstice between the bottom of the pouch 34 and the second ply that is filled with a lubricating fluid such as mineral oil to reduce massage friction the ply associated with the pouch 34 may thereby move somewhat independently of.
