Help with Extensor Indicis Muscle Injury and Pain

Cold Therapy Gel Back of the Wrist, Hand, and Finger

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relieve for new injuries and is great as a maintenance treatment for overuse and repetitive use injuries such as tennis elbow. Cold therapy should be used on new and recent injuries instead of heat as it cools the area much like ice and does not promote swelling. A recent study showed that Biofreeze decreased pain 2 times more than ice and the pain relief lasts 9 – 10 longer. Rub the gel into the back of the forearm down to the wrist, back of the hand and into the first finger.

Warm Therapy Gel For Extensor Muscle, Arm, Elbow and Hand Injury and Arthritis Pain

For arthritic or chronic shoulder, arm, elbow and hand pain relief I recommend Sombra Warm Therapy Pain Relieving Gel. Sombra provides warmth without burning and is better at relieving pain than other over the counter pain creams. To relieve extensor indicis muscle pain apply Sombra all around the elbow and down the back of the forearm, into the wrist, hand, and fingers.

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

Compression Band for Tennis Elbow, Golf Elbow, Carpal Tunnel Syndrome, Repetitive Stress Injuries

The BandIT Forearm Band is worn by many professional athletes to prevent and relieve muscle pain caused by repetitive motions of the elbow and wrist. The BandIT uses selective pressure on the forearm muscles without cutting off circulation, limiting range of motion or causing swelling around the band. Though I do not recommend this as a long-term treatment or for long-term wear, the BandIT can help relieve pain for athletes to help get through a game or for those who suffer from carpal tunnel syndrome that want pain relief while typing to make a deadline. Read and follow the enclosed instructions for temporary relief from forearm, wrist, hand, and finger pain.

Compression Gloves For Support, Warmth and Pain Relief

Whether the pain in your hands is caused by 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 are reinforced so that they will not fray with wear or during washing. I like this particular brand because the gloves are easier to get on and off than most other compression gloves. Reasonably priced too!
