What is Carpal Tunnel Syndrome?

By on June 25, 2012 in Diseases, Health with 0 Comments


The carpal tunnel syndrome is a painful and progressive condition that occurs when the median nerve, which runs from the forearm into the hand, becomes pressed into the carpal tunnel and is trapped. It occurs in the wrist area and the start of the hand.

The carpal tunnel is a delicate and narrow channel or passageway of ligament and bones of the hand by crossing the median nerve, tendons and nerves.

The median nerve is responsible for controlling the feelings of the palmar aspect of the thumb and fingers, except the little finger and several pulses of small muscles in the fingers that allow them to move.

As a result of inflammation and swelling of the tunnel, there is an intense pain in the hand and it becomes weak and numb, after which the use of the hand and wrist becomes quite limited. It then expands to the rest of the arm.

What are the symptoms of carpal tunnel syndrome?

Symptoms appear gradually, with sensations of heat, numbness, itching and tingling in the palm and fingers. Generally, those who suffer from carpal tunnel syndrome report that their fingers feel swollen and numb or as if they were useless. However, there is still no swelling or inflammation.

These often appear on one or both hands and, above all, during the night. In several cases, the person feels the need to shake the wrists on awakening, as if asleep on his hands and wrists at night.

Over time, it becomes difficult to tighten the grip, you lose strength and your hand becomes very difficult to use. In chronic cases, where there is no treatment or where treatment is not adequate, the muscles will atrophy and you can also lose the sensations of cold and heat.

What are the causes of carpal tunnel syndrome?

Many times, this syndrome occurs as a result of various factors that increase pressure on the nerve and tendons, leading to problems in the functioning of the midrib. Generally, it is believed that the problem is due to a congenital predisposition.

Other factors that also affect the syndrome are wrist injuries that cause inflammation, such as a sprain or a fracture.

You can also consider factors such as hyperactivity in the pituitary gland, hypothyroidism, rheumatoid arthritis, mechanical problems in the wrists, fluid retention (especially during pregnancy and menopause), and a cyst or tumor in the tunnel.
