    Whether the pain in your hands is caused by trigger points, a muscle injury or arthritis, compression has been shown to help with pain relief. The Imak Compression Arthritis Gloves are some of the best on the market.

    The gloves provide gentle compression, which helps decrease both pain relief and inflammation. The seams of the gloves are sewn to the outside so you will not have irritation or discomfort. The fingers opening is reinforced so that they will not fray with wear or during washing.

    To determine your size, measure straight across the widest part of your palm. Extra small: up to 2 3/4 inches wide. Small: up to 3 1/8 inches across. Medium: up to 3 1/2 inches across. Large: up to 4 inches across. Extra large: up to 4 1/2 inches across.

     

    The Neo G Medical Grade VCS Wrist and Thumb Support provides adjustable wrist support and compression to the wrist. The brace allows full movement of the hand, fingers, and thumb while providing support to the wrist.

    Extensor Indicis Trigger Point Treatment

    The extensor indicis muscle can be self-treated. Because muscle trigger points tend to occur in several muscles simultaneously, you will also need to check and treat other muscles in the arm, shoulder, and chest.

    TWD highly recommends The Trigger Point Therapy Workbook. It is an excellent resource to learn how to find and treat trigger points not only in the arm but throughout the body.

    Another option is to find a massage therapist, chiropractor, or physical therapist who has trained in trigger point therapy. They will show you how to find and treat specific trigger points.

    Trigger points respond best to several 1-2 minute treatments spread throughout the day. Continue treatments until pain and symptoms do not occur when pressure is applied to the area surrounding the Trps.

    Sombra Warm Therapy Gel is recommended for relaxing muscles and relieving pain. It warms without the burning heat of other gels. An excellent choice for pain caused by trigger points, muscle/joint over-use and stiffness, and arthritis. If you have reoccurring muscle cramps or pain, you should keep Somba on hand, it provides almost instant relief. (Not sold in stores)

    Biofreeze Pain Relieving Gel is an excellent pain-relieving gel recommend for those who have sudden onset muscle pain or recent injuries.  It is better to use than warm therapy gels and creams for muscle pain caused by inflammation as it cools the area much like ice. If your pain is from a recent injury use Biofreeze. It is excellent to use on sprains, strained and sore muscles and joints.

    The CompressionZ Compression Arm Sleeves are for those who want or need more support for muscle injury, muscle recovery or lymphedema. The sleeves work well for those who have chronic elbow, forearm and wrist pain due to repetitive motions that can irritate the extensor muscles in the arm. The sleeves work well for athletes as well as people whose jobs require repetitive twisting motions of the wrist. The sleeves are available in 3 sizes and a variety of colors. Be sure to read the size chart and follow the instructions to ensure proper fit. Two sleeves per package
