TENS machines work by sending low-voltage electrical impulses through the skin to stimulate the nerves and reduce pain. When a TENS machine is used for sciatica pain relief, the electrodes are typically placed near the site of the pain, such as the lower back.
The electrical impulses generated by the TENS machine interfere with the transmission of pain signals to the brain. They also stimulate the production of endorphins, which are the body’s natural painkillers.
TENS therapy has been shown to be effective in reducing sciatica pain in some people. However, the exact mechanism by which it works is still not fully understood and the evidence for its effectiveness varies.
It’s important to keep in mind that TENS is not a cure for sciatica, and that it may not work for everyone. It is best used as a complementary therapy in combination with other treatments, such as physical therapy and pain medications, to help manage pain symptoms.
Before using a TENS machine for sciatica pain relief, it is important to consult with a healthcare provider to ensure that it is safe and appropriate for your specific condition. They can also advise on the proper use of the machine and help determine the best setting for your individual needs.
