Hi
I think your doing everything right,moving around trying to disperse it,is probely the best cure.
Windeze/deflatine etc was a waste of time for me.
Peppermint tea and a hot water bottle helped for me(and still does after 2 1/2 yrs)
Your only 1 week post op your body may just need more time to rid of the gas used in the operation.
It will pass,just take it slowly when your eating/sipping,don't be afraid of eating as its not good for your body and healing.
You will be fine x
