Carpal Tunnel Syndrome
Carpal tunnel syndrome is an entrapment of the median nerve that causes paresthesia, pain, numbness, and other symptoms. Some of the predisposing factors include: diabetes, obesity, pregnancy, hypothyroidism, and heavy manual work or work with vibrating tools.
The main symptom of CTS is intermittent numbness of the thumb, index, long and radial half of the ring finger. The numbness often occurs at night, with the hypothesis that the wrists are held flexed during sleep. Pain in carpal tunnel syndrome is primarily numbness that is so intense that it wakes one from sleep.
