Does local cryotherapy help with some diseases?

Localized or spot cryotherapy is more effective than whole body cryotherapy in the treatment of  particular most affected areas. It is used to minimize pain, promote healing, treat wounds and swelling. This type of cryotherapy can be applied to any specific injured part of the body such as the ankles, shoulders, feet, elbows, knees, and neck. Seems that local cryotherapy is ideal for athletes and active people who are susceptible to injury. But localized cryotherapy has its application in other spheres, like the beauty industry and medicine. 

In medicine it is used in different chronic conditions to inhibit inflammation, to reduce pain and spasms, to decrease muscle tension, to improve blood circulation, for immunomodulation, etc. Localized cryotherapy has shown good results among people who suffer from chronic pain due to arthritis or inflammatory conditions and those who are recovering from an injury or surgery. 
Localized cryo sessions are prescribed to people who suffer from acne, psoriasis, eczema, as they help to reduce redness of the skin, irritation and itching. Also, it helps to minimize scars.
