Final answer:
Carpal tunnel syndrome is a probable cause of the symptoms described, and treatment options include wearing a wrist splint, corticosteroid injections, or surgery. Without treatment, the muscles in the affected hand may weaken and waste away.
Step-by-step explanation:
The symptoms described are consistent with a condition called carpal tunnel syndrome (CTS). CTS occurs when the median nerve, which runs through the carpal tunnel in the wrist, is compressed or irritated. This compression can cause pain, numbness, and weakness in the affected hand and fingers.
To alleviate symptoms, treatment options include wearing a wrist splint, receiving corticosteroid injections, or undergoing surgery to release pressure on the median nerve. Without treatment, the muscles in the hand may weaken and waste away.
