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.
These devices are predominately used for acute and chronic nerve-related pain. Your physician may prescribe a TENS machine as an alternative to, or in addition to, pain medication. It effectively can help control your pain. TENS units are often small, portable devices that are convenient to use at home or work.
