The triceps muscle sits at the back of the upper arm and straightens the elbow; as in performing dips in the gym or extending the arm to take money. Injuries or problems with the triceps muscle are very rare. Occasionally the muscle can be strained after unaccustomed loading, as in some gym or DIY activities but the discomfort usually settles quickly over two or three days and no treatment is necessary.
Weakness of the muscle is usually associated with neck problems that will be dealt with separately under ‘neck pain’.
