When?
Use hot and cold when you are suf­fer­ing from acute pain, if your painkillers are not work­ing. It can be use­ful before you go to bed or if you wake in the early morn­ing. It may also ease the pain if you feel sore after a treatment.

How?
Cold - Use any of Nature Cre­ation nat­ural ther­apy packs, which will fit com­fort­ably to the area of pain.
Hot — com­press the heated Nature Cre­ation nat­ural ther­apy packs onto the pain area (fol­low the instruc­tions included with the pack).

Cau­tion!
Do not apply either the Nature Cre­ation hot or cold ther­apy pack directly to your skin but wrap them in a tea towel or sim­i­lar to pre­vent burn­ing. Make sure the wrap­pers are of a sim­i­lar size.

Cold -> Hot -> Cold
Start with cold and fin­ish with cold. Apply each pack to the area of pain for five min­utes and leave 15 min­utes before repeat­ing. You can repeat this process as many times as you like, but the first cou­ple of ses­sions are usu­ally the most useful.

Why?
Using hot and cold acts like a local pump cold push­ing blood from the area, warm bring­ing fresh blood into the area, the valves in the veins cause the blood to cir­cu­late reduc­ing the level of inflam­ma­tion in the blood stream. If you can reduce the inflam­ma­tion this will decrease the pain and help you keep more mobile and recover sooner.
