Event Description

This spontaneous case was reported by a consumer and describes the occurrence of burns third degree ("he believes he has third degree burns even though it has not been verified by hcp") in a (b)(6)-year-old male patient who received aleve tens device direct therapy unit for back pain.The occurrence of additional non-serious events is detailed below.Other product or product use issues identified: device ineffective "this is supposed to relieve pain not give pain" and device stimulation issue "i was shocked" (seriousness criterion medically significant) over a period of 20 min.On an unknown date, the patient started aleve tens device direct therapy unit.On an unknown date, the patient experienced burns third degree (seriousness criterion medically significant) with erythema and mobility decreased ("the shock caused me to become immobile / loss of movement in right side by shock").Aleve tens device direct therapy unit was withdrawn.At the time of the report, the burns third degree had not resolved and the mobility decreased had resolved.The reporter considered burns third degree and mobility decreased to be related to aleve tens device direct therapy unit.The reporter commented: that he was about 5 minutes into using the device when he experienced an electrical shock that lasted about 20 minutes or so, it was stinging to the point it felt like it was burning him.The stinging was so excruciating he could not reach the remote to turn it off because of the pain it was giving and immobilized the right side of his body which lasted several minutes before he could use his whole body again.Reporter stated it left red marks where the patch was in my back and he think he has third degree burns even though it has not been verified by an hcp.He used the device several times prior to his experience and never had the events experienced this last time and he has not received medical treatment or is using anything to treat the red marks or the third degree burns.Diagnostic results (normal ranges are provided in parenthesis if available): body mass index was 20.8 kg/sqm.Most recent follow-up information incorporated above includes: on (b)(4) 2018: following internal review the code of event "the shock caused me to become immobile / loss of movement in right side by shock" was changed from pt "hemiparesthesia" to pt "mobility decreased".On (b)(6) 2018: no new clinical information.On (b)(6) 2018: no new clinical information.This spontaneous report refers to a (b)(6) year-old male patient who used aleve tens device direct therapy unit (transcutaneous electrical nerve stimulation (tens therapy)) since unspecified date (used the device several times) for back pain.Five minutes into using the device, he experienced an electrical shock that lasted about 20 minutes or so, the shock caused him to become immobile / loss of movement in right side by shock (non-serious event upon follow-up).Reporter stated it left red marks where the patch was in his back and he believes he has third degree burns even though it has not been verified by hcp (health care professional).The events are considered serious due to medical importance and are unlisted according to aleve tens reference safety information.This case lacks information for a comprehensive assessment, including intensity after turning the device on, treatment mode when event was experienced and presence of any implantable electric or metallic device.However considering the mechanisms of action of suspect product, the close temporal relationship and the nature of reported event, causal or contributory role of aleve tens to the events cannot be excluded.Further information was requested.This case was regarded as incident.
