I have a lot of pain- most or it related to nerve damage and vitamin deficiency muscle aches. So I am always looking for something to help with this issue. Most of my pain actually occurs on my feet because that is where common nerve damage aches go. When I received the #tensunit by Santa Medical I was skeptical. But now I am a believer! This tiny little unit gives so much zap and muscle pressure and you can really change it up for exactly what you need at the moment. You can do different types of pressure like kneading or or massage or even a simple beat. You control the intensity and put the sticky pads exactly where the pain is so you can control the feeling. It had a lot of power, this little machine. It goes up to a level 10 and I didn’t need anything more than a level 4 for my pain.
