Lumbrical Muscles of the Hand Pain Relief Recommendations

Cold Therapy Treatment For Pain In The Back of the Hand and Fingers

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relieve for new injuries and is great as a maintenance treatment for over use injuries.  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 times longer. If you have recently injured the hand’s lumbrical  muscles or have unexplained pain that has started in the back of the hand extending into the index and small fingers, use Biofreeze. Rub the gel into the back of the hand and fingers for pain relief.

Warm Therapy for Post Injury, Chronic Hand and Finger Pain

Sombra Warm Therapy Gel is a pain relieving gel that I use both personally and professionally in my massage therapy practice. It provides warmth without burning heat like other over the counter heating creams and gels.  It works well for post injury pain and stiffness. It is great for chronic arthritis pain as it can be applied several times a day. Apply Sombra to  the back of the hand and into the fingers to ease lumbrical muscle 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!

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.
