Final answer:
Injury to the median nerve is responsible for symptoms of Carpal Tunnel Syndrome, such as pain, numbness, and tingling in the thumb and first two fingers. Treatment options range from splints to surgery, with the latter generally providing the most effective relief.
Step-by-step explanation:
The injury to the median nerve accounts for symptoms such as pain, numbness, and tingling in the thumb and the first two fingers of the hand. This condition is known as Carpal Tunnel Syndrome, which occurs when the median nerve in the wrist becomes compressed, particularly under the carpal ligament. Compression of the median nerve leads to inadequate nervous stimulation of the muscles in the affected digits. Treatment options include wrist splints, corticosteroid injections, and surgery to cut the carpal ligament, which can relieve pressure on the median nerve and generally provides a more effective resolution than nonsurgical treatments.
The median nerve is a systemic nerve of the arm situated between the ulnar and radial nerves, playing a critical role in the sensory and motor functions of the hand. Without proper treatment, prolonged compression of the median nerve may cause the muscles in the hand to weaken and atrophy.
