Underlying health conditions like arthritis or gout can also cause knee problems. Some pain begins mildly then worsens over time. Fortunately, there are practical solutions to treating acute and chronic knee pain without medications. Transcutaneous Electrical Nerve Stimulation or TENS therapy uses mild electrical pulses to relieve pain. If you struggle with discomfort, find out how using TENS for knee pain can help you. 

The knee is one of the most complex and largest joints in the human body. It is made of bones, cartilage, ligaments, and tendons, responsible for bending or straightening the body. In particular, it bears a great deal of stress from repeated motions like walking or running every day. It also absorbs shocks from high-impact activities, such as jogging, squatting, or lifting weights. Therefore, it is vulnerable to many injuries and overuse. Sudden movements and chronic conditions can strain the knee and cause swelling or numbing sensations. The TENS for knee pain uses small electrical currents to reduce pain symptoms. iTENS Australia offers revolutionary pain management through the wireless iTENS machine.

Minor knee pain or strains can heal on their own. In more severe cases, physical therapy, knee braces or surgery may be needed. Using TENS can also help relieve chronic pain and soreness from post-surgery. TENS devices send mild electrical pulses from its electrodes to the nerves through the skin. The electrical currents flood the nervous system and intercept the transmission of pain signals to the brain. It also triggers the release of natural pain relievers called endorphins. As a result, TENS reduces the overall pain perception. In particular, the iTENS has a set of wireless electrodes and is capable of Bluetooth connectivity allowing for easy and convenient use. The electrodes fasten to adhesive gel pads to stick to the skin in different body parts. You can effectively perform TENS for knee pain treatments with the iTENS.

Chronic pain is a condition where the affliction recurs for an extended period of time. For example, illnesses like arthritis are long-lasting or progressive. Some people resort to oral painkillers to manage pain when it strikes. Others undergo physical therapy or exercise to deal with pain. Using TENS for knee pain is an effective strategy to ease discomfort while you are working, on the move, or exercising. Additionally, the electrical stimulation helps boost blood circulation to the area. TENS increases the blood flow to the knees relaxing sore muscles and damaged nerves. Therefore, it accelerates the healing of injuries and post-surgery pain.
