Biceps Brachii Muscle Pain And Trigger Points


The biceps brachii: A muscle loved by men and women that may be your source for tendonitis at your inner elbow, or for shoulder pain. There it may even mimic shoulder bursitis.


If you are a craftsman or an ambitious athlete you may suffer from sore trigger points, or tender areas in this muscle. Of course, others may also tender or trigger points in this muscle.

Pain Zone


As you can see in the two pictures below, pain that is created by trigger points in your biceps brachii can radiate down into your elbow and into the front of your shoulder. You even might experience a slight pain at the side of your shoulder and/or your upper back.


This way your biceps may contribute to your



The intensity of the red areas indicates how common pain in the respective zone is experienced when trigger points are present. The darker the red, the more common the pain is.



Attachment Points


The biceps has two muscle bellies. That is why it is named Biceps. There is a long one, the caput longum and a short one, the caput breve.


It has two attachment points at the shoulder, and one at the forearm.In the shoulder, it inserts at the processus coracoideus, the bony knob that you can feel at the front of your shoulder, and on the shoulder blade. At the forearm, it attaches at the upper side of the radius.


Note: The processus coracoideus actually also belongs to the scapula/shoulder blade.


Function Of The Biceps Brachii


The biceps´ best known function is the flexion of the elbow. When in a flexed position, the biceps brachii also supinates the hand, that is, it turns the palm upwards.


In addition, the short part – caput breve – of the biceps elevates the arm. The long part – caput longum – abducts the arm and rotates the shoulder inward.

Biceps Overuse And Trigger Point Development


Certain  activities and movements may lead to trouble with the biceps.


If you are an athlete, especially a climber, swimmer or someone who exerts heavy throws – e.g. Baseball player –, you need to take care of this muscle.  Strong or repetitive supination of the hand, which occurs, for example, when you have to torque a reluctant screw, can cause trouble over time.  If you are unused to movements like this, or if you are not in a balanced muscular state, your biceps might cause you problems.


Impaired Or Painful Movements


If you suffer from trigger or tender points in this muscle, or if it is just very tight you might have difficulties and/or pain when…

  • … lifting your arm  in front of you above shoulder level
  • … bending your arm
  • … abducting/spreading  your arm


Biceps Brachii Muscle Palpation


Finding this muscle is a no-brainer. Just pinch the muscle at the front of your upper arm and you will have the biceps brachii between your fingers.


Biceps Brachii Muscle Self-Massage


Massaging the muscle is also quite simple. You will use your knuckles to massage your biceps.

Use slow downward strokes and pay special attention to the mid-section of the biceps. This is the area that usually needs the work as trigger or tender points are most likely to develop here - indicated by the Xs shown under attachment points -.
