How Cryotherapy Works for Your Feet and Ankles
Cryotherapy has gained traction in various medical fields for its ability to alleviate pain and reduce inflammation. For us at Desert Podiatric Medical Specialists, this “freeze therapy” is a minimally invasive approach to treating a range of foot and ankle conditions and getting our patients back on their feet. In this article, we’ll explain how cryotherapy works, its benefits, and what’s important to know before giving it a try.
How Cryotherapy Works
Essentially, the application of extreme cold to the skin and underlying tissues triggers key responses. Initially, there is vasoconstriction, or a narrowing of the blood vessels, which helps to reduce blood flow to the treated area.
This is followed by vasodilation, a widening of the blood vessels, as the body works to restore normal temperature. This cycle between these 2 states flushes out the bad stuff and promotes healing. Cold temperatures also naturally slow nerve conduction, which can effectively reduce the sensation of pain in the treated area.
Benefits of Cryotherapy for Foot and Ankle Conditions
Besides controlling inflammation, cryotherapy offers a range of benefits for various foot and ankle issues. Pain reduction is a primary advantage because the cold can temporarily numb nerve endings and decrease the transmission of pain signals to the brain. But how do these benefits apply to real foot conditions?
- Muscle Spasms: Cryotherapy can help to relax tight muscles and alleviate discomfort.
- Nerve Pain: such as Morton’s neuroma or peripheral neuropathy, the cooling effect can provide temporary relief by desensitizing the affected nerves.
- Plantar Warts: Cryotherapy is a well-established method for the removal of warts, where the extreme cold freezes and destroys the infected tissue.
- Plantar Fasciitis: The cold helps to reduce the inflammation within the plantar fascia.
- Achilles Tendonitis: Decreased swelling of the tendon and reduced pain associated with inflammation.
- Ankle Sprains: Cryotherapy helps to constrict blood vessels, which minimizes swelling and reduces the formation of bruising around the injured ligaments.
Important Considerations for Cryotherapy
While cryotherapy can be beneficial, it’s not perfect for everyone. It should be used cautiously in those with certain conditions, such as peripheral artery disease or impaired circulation. Prolonged or improper application can also lead to skin damage or frostbite (yes, even in Tucson!).
For instance, individuals with sensory deficits, such as those with peripheral neuropathy, may not be able to accurately gauge the level of coldness and could be at a higher risk of skin damage. It is also not best for direct application to open wounds or areas with compromised skin integrity.
