Help with Extensor Carpi Ulnaris Muscle Injury Pain

Cold Therapy Treatment For Wrist PainBiofreeze is recommended for recent muscle injury

Biofreeze Pain Relieving Gel is a cold therapy gel that provides pain relief for new injuries and is great 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 extensor carpi ulnaris muscle or have unexplained pain that has just started in the wrist, use Biofreeze. Rub the gel into the elbow down the back of the arm to the wrist. You can also apply it to the outside of the hand and wrist for pain relief.

 Elbow / Wrist Ice Wrap For Cold Treatment and Compression

DonJoy Wrist and Elbow Cold WrapPain caused by the extensor carpi ulnaris mimics a sprain.  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. 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.

Warm Therapy for Post Injury and Chronic Wrist / Hand Pain

Sombra Warm Therapy Gel provides pain relief. 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.  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 all around the elbow, into the back of the forearm and into the outside of the hand and little finger to ease the pain. 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.

Wrist Brace To Support and Relieve Wrist Pain

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


The Neo G Medical Grade VCS Wrist and Thumb Support provides adjustable wrist support and compression to the wrist.

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 a treatment or for long term wear, the BandIT can help relieve pain for athletes to 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.

Self Treatment For Extensor Carpi Ulnaris Muscle Wrist Pain

Do you know that small “knots” or other dysfunction in the extensor carpi ulnaris muscle can cause pain that mimics a sprained wrist?  It can also make it difficult to impossible  to twist your wrist as you would to open a jar or turn a screwdriver.  

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 unresolved wrist pain and find it difficult to twist your wrist without pain it maybe trigger points in the extensor carpi ulnaris 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.
