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.
The physician ordering the TENS unit must be the attending physician or a consulting physician for the disease or condition resulting in the need for the TENS unit. If the TENS unit produces incomplete relief, further evaluation with percutaneous electrical nerve stimulation (PENS) may be indicated.
