The Therafoot Pro Ems Foot Massager is designed to provide relaxing foot therapy. However, like any device, it may come with potential side effects that users should be aware of.

Some users have reported mild discomfort during their first few sessions, as the electrical stimulation can feel unusual. It is always advisable to start at a lower intensity and gradually increase it to find your comfort level.

Other possible side effects may include temporary redness or tingling in the feet, which should subside shortly after use. If you have any underlying health conditions, it’s best to consult a healthcare professional before starting treatment.
