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.
Other Precautions: 1  Use caution in your daily activities. TENS may suppress the sensation of pain that your body uses to tell you when something is wrong. 2  Use TENS only for the condition for which the device is ordered. Talk to your doctor if you have any change in your condition or if a new condition develops.
