Cold Therapy Treatment For Pain In The Fingers

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relief for new injuries and is recommended as a maintenance treatment for overuse injuries.  Cold therapy should be used for 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. If you have recently injured the flexor digitorum profundus muscle or have unexplained pain that has started in the fingers, use Biofreeze. Rub the gel around the elbow, down the inside of the forearm and into the wrist and hand.

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

Sombra Warm Therapy Pain Relieving Gel  is a pain relieving gel that I use both personally and professionally in my massage therapy practice. It provides warmth without burning heat that is associated with other heating creams and gels. It works well for post-injury pain and stiffness as well as chronic arthritis pain as it can be applied several times a day. Apply Sombra to the inside of the elbow, down the back and inside of the forearm. Also apply to the hand and fingers to ease the pain of the flexor muscles.

NOTE: Do not use Sombra Warming Gel when using ice packs or heat packs as there is a risk of blistering the skin. For the most effective treatment, apply 5 to 10 minutes before putting on a brace or sleeve.

The brace can be used on either hand and has two Velcro closures that can be adjusted for comfort.

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 finger openings 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!
