Got aching muscles after all that holiday wrapping? You need pain relief — and fast.
While booking a massage will help work out sore muscles, you need something stronger if you're dealing with a recurring pain issue. That's where a TENS massager can help. And, just for today, Amazon has the top-rated Nursal TENS massager on sale for an impressive 52 percent off.
If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And even those without Prime get free shipping on orders of $25 or more).
Not familiar with TENS massagers? These handy devices deliver small electrical impulses through electrodes with adhesive pads that attach to your skin. The goal, according to the Cleveland Clinic, is to help tamp down on pain in those areas.
There are two main theories on how TENS — which stands for transcutaneous electrical nerve stimulation — works. One is that the electric current stimulates nerve cells that block the transmission of pain signals, and modifies your perception of pain in the process. The other is that the nerve stimulation raises the level of endorphins, which are your body’s natural pain-killing chemical. Those endorphins then block the perception of pain.
TENS massagers can be used to treat a range of conditions, but they tend to be most successful with conditions like osteoarthritis, bursitis, tendonitis, low back pain and fibromyalgia, the Cleveland Clinic says.
A TENS massage was traditionally done at your physical therapist's office, but there are now at-home devices you can use to get relief without having to leave your place.
Enter the Nursal TENS massager. This handy device features 24 different modes for pain relief, allowing you to control the intensity and pattern of your electrical pulses.
The Nursal TENS massager offers up to 20 hours of continuous use, and can be easily fired up agin with a wall charger, power bank or USB port when the battery runs low.
A convenient timer lets you set your session from anywhere between 10 and 60 minutes, while this device's portability and easy carrying case means you can take it anywhere.
Reviewers rave about how well this little device works. "This unit's power output has been as strong and effective as the large professional unit in my chiropractors office," a five-star fan, who uses it for their lower back pain, said. "It's so much more convenient then going into the office. It has a bright lighted blue display which shows all functions and settings in the palm of my hand. ...Dollar for dollar I feel this was the best unit available. I researched pretty much all of them before making this purchase."
A fellow happy customer called this TENS unit "powerful," noting, "I’ve been using this TENS unit for a few days several times a day for very bad lumbosacral pain that has been chronic, having to take pain medication daily. And so far I am greatly helped and relieved of the pain by this unit and have not had to take any pain meds —this is amazing!"
One satisfied reviewer simply put it this way: "The pain relief is REAL people. Lyme, Fibromialga, Arthritis, or just sore muscles. This little gadget is fabulous. It gets me through the tough days. And even the not so tough but sore from working out days too!!!!!"
Again, this sale is just for today — don't miss your chance to get your own TENS massager at a sweet discount!
