    Where Is The Coracobrachialis Muscle?

    Corocobrachialis Muscle Showing Trigger Point Location

    The coracobrachialis lies toward the inside of the upper arm and attaches the shoulder blade (coracoid process) to the bone of the upper arm (humerus).

    What Movements Does It Control?

    • Raises arm to the front of the body (shoulder flexion)
    • Pulls the arm in toward the body (adduction of the arm at the shoulder)

    Jar grips should be in every kitchen to open jars and bottles to help prevent injury to the arm extensor muscles. So many painful arm, wrist, and hand injuries happen while trying to open sealed lids on jars. Great for those with hand and wrist arthritis. Works on doorknobs too!

    What Causes Trigger Points In the Coracobrachialis?

    • Reaching your arm/hand around the back of your head
    • Push-ups
    • Rock or rope climbing
    • Throwing a ball
    • Golf
    • Tennis
    • Lifting heavy weights with outstretched arms and palms facing up

    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 the 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 wants pain relief while typing to make a deadline. Read and follow the enclosed instructions for temporary relief from forearm, wrist, hand, and finger pain...

    Coracobrachialis Trigger Point Treatment

    Coracobrachialis trigger points do not need additional tools for treatment. You will use your thumb to massage the muscle. The muscle can be hard to find, and you must be aware of the blood vessels that lie under the muscle.

    Trigger points in the coracobrachialis will contribute to other trigger points developing in other muscles in the arm that will also need treatment. The Trigger Point Therapy Workbook is an excellent resource for those interested in self-treating muscle pain. It explains what trigger points are, how they develop, and how to find them, and methods of treatment.

    Another option is to find a massage therapist, chiropractor, or physical therapist trained in trigger point therapy. They will show you how to find specific trigger points related to your pain and show you how to do self-treatment at home.

    For the best outcome, trigger points need several treatments of 1-2 minutes throughout the day.

    Sombra Warm Therapy Gel is recommended for relaxing muscles and relieving pain. It warms without the burning heat of other gels. An excellent choice for pain caused by trigger points, muscle/joint over-use and stiffness, and arthritis. If you have reoccurring muscle cramps or pain, you should keep Somba on hand; it provides almost instant relief. (Not sold in stores)

    Biofreeze Pain Relieving Gel is an excellent pain-relieving gel recommend for those who have sudden onset muscle pain or recent injuries.  It is better to use than warm therapy gels and creams for muscle pain caused by inflammation as it cools the area much like ice. If your pain is from a recent injury, use Biofreeze. It is excellent to use on sprains, strained and sore muscles, and joints.

    The Nordic Lifting Elbow Support Sleeves provides excellent support but also because it is comfortable to wear. The sleeves do not bind or limit mobility, and they stay in place. The sleeves are available in 4 sizes. If you deal with elbow pain or need some extra support for tennis, golf, or other activities, this sleeve is what you need.
