I bought a medical treatment wristband named "anti-nausea wristband, rechargeable relieve nausea motion sickness bands, relieve nausea electrode stimulator wrist bands relief for anxiety, migraine, motion sickness" on amazon recently.Website:https://www.Amazon.Com/dp/b0b7b7g92p i used the wristband follow the instructions.Unfortunately it made me uncomfortable and i found some erythema and blisters appeared on my wrist.I took two pictures of my wrist and i put them in the attachment of this document.I searched this wristband name on the website of fda establishment registration and device listing and 510(k) premarket notification, but i could not get any records in fda databases.I wonder how could amazon permit this medical treatment wristband shelved without fda establishment registration or 510(k) premarket notification.What's more, i collected some information through it's web page on amazon.(b)(6).
