Carpal Tunnel syndrome (CTS) symptoms usually increase gradually and may initially only be present at night. Carpal tunnel syndrome may be in one or both wrists.
A dull ache in the wrist, forearm (worse at night) in so radiates pain to the, elbow, shoulder, hands, thumb and fingers (excluding the little finger). There will be tingling or burning in the hand or four fingers. Weakness in the fingers and hands may be present.
Carpal tunnel syndrome can be caused by a number of factors; A traumatic wrist injury such as broken or sprained wrist, repetitive use of the wrist (Carpal tunnel syndrome is a form of RSI).
Pregnancy - causing fluid retention in the wrist. The use of vibrating machinery.
Congenital - some people naturally have a smaller, narrower carpal tunnel.
All of these conditions can cause a narrowing of the space through which the median nerve passes. The cause may be structural such as with a fracture or congenital cases, or due to swelling, inflammation or fluid retention.
Carpal tunnel syndrome is 3 times more common in women, probably because they have a smaller carpal tunnel. It also has a higher prevalence in people with diabetes and other conditions which directly affect the nervous system. It usually occurs firstly and sometimes solely in the dominant hand, where it is also more painful. Some professions are more at risk of developing carpal tunnel syndrome, especially people working on an assembly line, who are continually repeating the same movement.
