It is safe for most people to use TENS/EMS. However, the electrical impulses that a TENS/EMS unit produces may cause a buzzing, tingling, or prickling sensation, which some people may find uncomfortable. In very rare occasions, an electrical current will be too intense for a patient, causing burning or irritation on the skin.
