What is TENS used for?
People use TENS to relieve pain for several different types of illnesses and conditions. They use it most often to treat muscle, joint, or bone problems that occur with illnesses such as osteoarthritis or fibromyalgia, or for conditions such as low back pain, neck pain, tendinitis, or bursitis. People have also used TENS to treat sudden (acute) pain, such as labor pain, and long-lasting (chronic) pain, such as cancer pain.
Although TENS may help relieve pain for some people, its effectiveness has not been proved.
Is TENS safe?
Experts generally consider TENS to be safe, although the machine could cause harm if misused. Have your physical therapist or doctor show you the proper way to use the machine, and follow these instructions carefully.
Always tell your doctor if you are using an alternative therapy or if you are thinking about combining an alternative therapy with your conventional medical treatment. It may not be safe to forgo your conventional medical treatment and rely only on an alternative therapy.
