Help with Extensor Carpi Radialis Brevis Muscle Injury Pain

Sombra Warm Therapy Gel provides pain relief.

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

For chronic arm, elbow, hand pain, and arthritis 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 muscle pain apply Sombra all around the elbow and down into the back of the forearm.

Cold Therapy Gel For Extensor Arm, Elbow and Hand Injury Pain

Biofreeze is recommended for recent muscle injury 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 and repetitive use injuries such as tennis elbow.  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. Many arthritis suffers like to use Biofreeze on swollen painful joints.

Elbow / Wrist Ice Wrap For Cold Treatment and Compression

DonJoy Wrist and Elbow Cold WrapThe extensor carpi radialis brevis can contribute to pain in the elbow, wrist and back of the hand.  It is important to treat the entire muscle for pain relief.  The DonJoy DuraKold Wrist and Elbow Ice Wrap is a good choice for this pain. I like this wrap because it can be used  for the elbow and forearm and repositioned for the wrist for wrist and base of the thumb pain. The wrap retains the cold for well over an hour, however, the recommended cold therapy treatment time is 20 – 30 minutes per session, longer treatment time could result in tissue damage.


Wrist Brace With Gel Packs

ActiveWrap Wrist and Hand Hot and Cold Wrap

Because twisting motions of the wrist can cause injury and irritate the extensor carpi radialis brevis muscle, a wrist brace can help relieve pain and provide support during repetitive twisting motions.  The ActiveWrap Compression Wrap for the Hand & Wrist not only provides compression and support to the wrist but also comes with insert gel packs for hot and cold treatment. The brace can be used on either hand and has two Velcro closures that can be adjusted for comfort.

The Neo G Medical Grade VCS Wrist and Thumb Support provides adjustable wrist support and compression to the wrist. The brace allows full movement hand, fingers, and thumb while providing support to the wrist. A good choice for those who need wrist support but need full mobility of the hand and fingers.

BandIT Therapeutic Forearm Band: 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 treatment or for long term wear, the BandIT can help relieve pain for athletes to help get through a critical game or for those who suffer from carpal tunnel syndrome that need pain relieve while typing to make a deadline. Read and follow the enclosed instructions for temporary relief from forearm, wrist, hand and finger pain.

Self Treatment For Extensor Carpi Radialis Brevis Muscle Elbow, Forearm, and Hand Pain

Do you know that small “knots” in the extensor carpi radialis brevis muscle can contribute to deep aching or burning pain in the back of the hand?  
The Trigger Point Workbook can help you resolve muscle pain throughout your body.
If this pain pattern sounds familiar  I  recommend that you purchase Claire Davies  The Trigger Point Therapy Workbook: Your Self-Treatment Guide for Pain Relief. Mr. Davies explains the trigger point phenomenon and muscle pain in everyday language.  But what makes this book worth its weight in gold are the individual muscle trigger point treatments that Davies has compiled. His diagrams and step by step instructions help you locate which muscles are contributing to your pain,  how to find the trigger point and treat it. It takes time and practice to master finding trigger points, but once you learn you have a tool and method to help relieve muscle pain throughout the body.  If you have burning pain in the back of the hand it may be trigger points in the extensor muscles of the arm. Deactivating trigger points can reduce or eliminate this pain. This book is a must have for anyone interested in finding the cause and treating muscle pain.
