Acute injuries come on suddenly and may be caused by a direct blow, a penetrating injury or a fall or from twisting, jerking, jamming, or bending a limb abnormally. Pain may be sudden and serve.
Overuse injuries occur when stress is placed on a joint or other tissue, often by “overdoing” an activity or repeating the same activity. Overuse injuries include.
Hairline cracks in bones of the arm (Stress fractures).
Pressure on nerves in the arm, such as carpal tunnel syndrome.
Treatment for an arm injury may include first aid measures (such as using a brace, splint or cast), “setting” a broken a bone or returning a dislocated joint to its normal position, physical therapy, medicines, and in some cases surgery. Treatment depends on:

CARPAL TUNNEL SYNDROME
CTS is also known as Repetitive strain injury (RSI) and its occurrence being common among keyboard operators, hairdressers and process workers.
WHAT IS IT?
CTS is pain numbness and tingling of the fingers (thumb and first three fingers only) caused by compression of the median nerve where it passes under the carpal ligaments.
Splinting the hands especially at night is also helpful. Corticosteroid injection in to the carpal tunnel is also claimed to be of benefit. In cases where loss of feeling in the hand and fingers is evident, a simple surgical operation to slit the ligament to relieve pressure on the median nerve is performed
