I have had many orthoscopic surgery’s and with some I have had the gas pains and with some I have not it’s just luck of the draw I gas. It will go away keep that in mind I know it’s extremely painful the gases are escaping from your body through your skin it’s not through your typical way hope walking does help. Another thing to keep in mind is do not drink water with ice ice will actually cause more gas maybe use the swabs for your mouth rather than the ice cubes good luck sweetie keep us posted
