Carpal Tunnel Syndrome (CTS)
What is it?
CTS is caused by compression of the median nerve at the “carpal tunnel” area of the wrist. It can be caused by a combination of factors, such as an injury that causes swelling, hypothyroidism, Rheumatoid Arthritis, mechanical problems of the wrist joint and genetic causes. Other external factors such as tumour or ganglions can cause pressure on the nerve.
The symptoms will tend to be mild at first and become worse over time, with numbness, tingling and a burning sensation of the thumb, index and middle fingers, this tends to be worse during the night and patients may experience a swelling sensation of the hand. Reduction of grip strength can also be present and if left untreated muscle wastage around the thumb and affected fingers can be seen.
