Upper Arm Pain
The most common injury in the upper arm is a broken bone (fractured humerus), however strains to the triceps and biceps muscles can also occur.
Injury to the Axillary nerve usually occurs as a result of a direct impact to the outer arm, although it can also be injured following a shoulder dislocation or compression of the nerve.
A humerus fracture is a break in the upper arm bone. This may be anywhere in the bone, from the neck of the humerus near the shoulder, to the distal end at the elbow. A form of fracture close to the elbow is known as a supracondylar fracture.
A tricep strain is a tear to the triceps brachii muscle at the back of the upper arm which contracts to straighten the elbow.
A biceps contusion is a bruising of the Biceps Brachii muscle in the upper arm. This occurs due to a direct impact to the area, usually from a collision or a ball, racket or stick etc hitting the arm.
