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.
Ive done business with company twice; first to buy the TENS unit then to buy a replacement cable. The price is great as is the product. It does what they claim and a bit more. I bought it to work my muscles but when my back became injured, I also used it for pain suppression.
