@soulyis01: The elbow hurts, and it hurts when you wring the can? Most of them got tennis elbows! Don't always take painkillers to treat the symptoms but not the root cause. Try to use this rehabilitation stick for centrifugal training. For a few minutes a day, home rehabilitation, playing ball and doing housework, office workers can use it!#tenniselbow #Golfelbow #theraputty #forearmstrengthener #
