The upper arm

The upper limb area (arms) between the shoulder and elbow is defined as the upper arm. Its bone structure includes only the humerus, which is a large tubular bone at the top with the bone head in the socket of the scapula and forms the elbow joint at the bottom together with ulna and radius. Surrounded by the relatively long humerus of numerous muscle groups, at the top of which also attach various muscles of the chest, back and shoulder muscles (especially the rotator cuffs). On the front of the upper arm are the so-called elbow flexors, the biceps (biceps brachii muscle), the brachialis muscle (upper arm muscle) and the coracobrachialis muscle (raven beak muscle). On the back is the extensor musculature (elbow stretches), the triceps brachii (also called triceps) and the anconeus muscle (elbow muscle).

Larger blood vessels in the upper arms are mainly the artery and the two venous branches of the vena basilica and the cephalic vein. In addition, numerous nerve tracts such as the radial nerve, the median nerve and the ulnar nerve and the connective tissue structures or fascia, in the nerves, blood vessels and muscles are embedded. Discomfort in the upper arm area is often due to impairments of the musculature, which due to the relatively cramped structures often also affect the nerve tracts and blood vessels. If, for example, as a result of incorrect loading, a permanent increase in the muscle tone of individual muscle groups can be trapped by a nerve and the pressure on the blood vessels cause circulatory disorders. In addition to upper arm pain, there are often sensations such as numbness or tingling, which can also occur in the care area of ​​the respective nerves and blood vessels.

Pain in the area of ​​the upper arm sometimes originates in the area of ​​the shoulder or the neck when muscles, nerves or blood vessels are in communication with the upper arm. In addition, the pain in a heart attack can radiate from the chest to the upper arm. If upper arm pain is accompanied by chest pain, a puncture in the chest, shortness of breath, upper abdominal pain or nausea and vomiting, an emergency doctor should be called as soon as possible.
