The cold pack is basically a plastic bag that contains water. Within the pack, lies another plastic bag or tube that contains ammonium nitrate fertilizer. When you hit the pack or place it against your body, the tube breaks and the water mixes with the fertilizer. An endothermic (heat absorbing) reaction follows, which causes the temperature of the solution to fall to about 35 F (1.6 Degree Celsius) for 10 - 15 minutes. Application of these packs can provide relief in case of pain, swelling, soreness, or burning sensation.

Carpal Tunnel Syndrome
Carpal tunnel syndrome is caused by compression of a nerve in the carpal tunnel. This is characterized by the sensation of tingling, burning or numbness, discomfort, and weakness in the hands and fingers. If the disorder is at a mild stage, then application of ice packs might provide adequate relief. This will not only lessen the intensity of pain, but also help reduce the swelling on the median nerve. Application of such packs will provide temporary relief from pain and soreness around the wrist.
The cold packs must be administered to the affected area at intervals of 10 - 20 minutes. It is always recommended to wrap a towel around it. This is to avoid direct contact of the cold pack with skin, which might otherwise cause pain and damage due to extreme cold. It would be best to use the packs that are recommended by your doctor.
Though the application of ice packs does not cure any medical condition, it can reduce swelling and provide relief from pain. The extreme cold that is used in this therapy, numbs the aching part and reduces the intensity of pain. This way, the user feels less or no pain at all. It is definitely better than taking painkillers or other medicines, as it does not give rise to side effects when used as recommended.
