Do Portable TENS Units Actually Work for Pain Relief
I suffer from chronic pain in my middle and upper back. The pain gets so bad at times, I have a hard time standing up. Chiropractic treatment helps keep my pain under control but due to insurance I can only afford to go once a month. So, I needed a solution that would reduce my pain between appointments. I heard about TENS Unit Electronic Pulse Massagers and decided to give one a try.
What Is a TENS Unit?
TENS stands for Transcutaneous Electrical Nerve Stimulation. These units use sticky electrodes placed on painful areas of the body. They deliver a current through the electrodes to the sore muscles. This feels like a tingling sensation. Higher settings can cause muscles to twitch. TENS units are FDA approved for over the counter use. If you've ever been to a chiropractor or physical therapist, you may have used a professional unit as part of your treatment.

Does chiropractic treatment cure back pain? Chiropractic therapy is a controversial treatment method but it may be helpful for some back pain sufferers.
How Do TENS Units Reduce Pain?
According to WebMD this isn't known. One possibility is they stimulate nerves and eliminate the sensation of pain.
Some people feel less pain when the electrical impulses are delivered. This could be because stimulating the nerves blocks other pain signals. Another theory is that stimulating the nerves may help the body produce natural painkillers called endorphins.

Do They Work?
My TENS unit doesn't eliminate my pain but it definitely helps. Simple household activities like laundry and cooking caused so much pain, I would have to lie down for an hour or two afterwards. Now I put on the electrodes, put the unit in my pocket, wrap the wires around so they don't get pulled out and I can remain on my feet without having severe pain afterwards. I have pain in different areas of my back, so I move the sticky electrodes every 15 minutes. It's become so much easier to get chores done and I don't have severe pain afterwards. Sometimes when my back pain is unbearable, I'll run the unit for a couple of hours and it helps a lot.
I did have a wrist injury recently though. I used the TENS unit to reduce the pain but it had no effect at all. Ultimately you'll have to try one to see if it works for your pain.
What You'll Need
Once you've purchased your TENS unit you'll need a few more things.
- Buy cotton balls and rubbing alcohol to clean your skin before putting on the electrodes. This will extend their lifespan. My electrodes last for several weeks before losing their stickiness.
- Buy a set of electrodes. My unit came with four. I bought a pack of 40. The ones I bought turned out to be larger and more effective than the electrodes that came with the unit because they cover a larger area.
- Buy rechargeable batteries and a charger. My unit requires 4 triple A batteries. It's cheaper to recharge them than to buy batteries often. Don't by a unit that requires batteries that can't be recharged. Icy Hot has a TENS unit that requires 3V CR2032 batteries. This could become expensive to operate.
- I bought Parker Labs Tensive Conductive Adhesive Gel to increase the life of the electrodes. It didn't work out for me. It was too sticky and messy. I bought the pack of 40 electrodes instead. It costs more but is less trouble. However, it's something you may want to look into.
- A box to put everything in. I bought a fancy box with a lid from Ross for $6. It's fits my TENS unit, electrodes, battery charger, alcohol and cotton balls. I keep it in the living room because it looks nice. It's a great way to keep your unit nearby without having your living room look like a pharmacy.
Which TENS Unit Should You Buy
I bought the Santamedical Tens Handheld Electronic Pulse Massager Unit. I've been using it for about 6 months without any problems. This is one of the most popular devices. The truMedic TENS Unit Electronic Pulse Massager is another popular and similarly priced unit. Both cost around $30-$40 and can be used with rechargeable batteries. Both offer the same features. There are others you can look into but these two brands are very popular and have lots of reviews you can read before making a decision.
