RhoGam is a vaccine like globulin shot that was developed in the late 1960s to keep a Rh negative woman from becoming sensitized to the Rh positive blood of her fetus in the unlikely event blood mixing occurs. Rhogam works very much like an immunization.
However, some new research has shown that TENS may be effective for reducing pain in people who have fibromyalgia, especially in combination with other treatments, such as exercise. Fibromyalgia is often treated with various medications to relieve pain and improve sleep.
It works on the superficial and spinal nerves traversing to the brain. TENS is a non invasive tool to assist with pain relief. Regular application of the TENs machine can result in reduced pain for up to 4 hours following use. TENs is considered a pain relief tool and not considered curative. The degree of pain relief declines with prolonged use; vaiation of electrode placement may combat this.
