1, many people think that the foot patch is amazing, and they are very nervous about when they can't use it. In fact, it is a superstitious view and should be rational.
2, the foot patch stimulates the plantar reflex zone, similar to massage. At most, it belongs to physical therapy products and has no pharmacological effect.
As can be seen from the above, no matter how your body is, you can use foot patches as long as you can soak your feet and do foot massage. If certain drugs or diseases prohibit such behavior, you just have to follow the doctor's advice. There's no need to be so nervous.
