Carpel tunnel syndrome is a disorder which occurs due to increased pressure on the medium of the wrist. This may give rise to paresthesias, muscle weakness or even numbness of the hand. The median nerve where the pain occurs is present in the carpel tunnel and from there other nine tendons pass by the forearm to the hand. This arises when the swelling in this tunnel builds pressure and puts it on the nerve. When the pressure develops to a great extent wherein it disturbs the working of the nerves, the person starts getting numbness, pain in the finger and hands or tingling.  

The reason why it occurs is still unknown to the experts. But there are several factors which can give rise to this disorder which can include persistent wrist bent, fractures, arthritis, swelling of the flexor tendons, joint dislocations etc. sometime during pregnancy, the fluid retention can also cause swelling in the carpel tunnel which then results into carpel tunnel syndrome. One can go for laboratory tests in order to diagnose this syndrome. If you are diagnosed by CTS then there are several treatments that will help in relieving from the pain. One has to take proper care of the wrist without putting much pressure on it.
