Rib cards are developed to reduce pain caused by pressure and friction with the lower ribs (6th and 7th ribs) during paddling during surf in. Paddling puts a warping chest posture so that the rib area is always stressed.If these conditions last for a long time, depending on your body making, the strain on the body itself will cause fattoma, and the skin and bone will become swelling.(It is also called paddle octopus or surfing octopus. If you continue to do more, the fatoma will harden and form small lumps.When the mass comes into contact with the bone, it will lead to sharp pain and it will also be conflicted on a paddle or on the board.There is no surgery to remove those hard clumps
