External Pain Relievers
One simple method to get relief from pain is by applying cold to the aching area of the body. This can be achieved using a frozen gel pack which comes in different shapes and sizes and is available at a nearby medical store. When something very cold is applied to the skin, it reduces the sensations of the skin by deadening nerve endings. This is exactly the principle used in a gel pack which can be cooled by refrigeration and applied to the affected part of the body to eliminate pain.
Colpac, a product of Allegro Medical is a kind of gel pack which can easily take different shapes to fit the body part and is thus a very good healing therapy for pain. A colpac after keeping in the freezer, can be applied to the painful area and it can give a cooling effect for 30 minutes at a stretch. They can be reused over and over again.
A knee wrap is another kind of external pain reliever which eases pain at the knees. If the knee wrap is not of the right type, it can lead to slip while bending or crouching. The knee wrap should be worn tight enough so that it releases the required power to enable us to stand up after squatting.
