Frostbite is a skin injury that happens after exposure to low temperatures. The skin freezes and blood vessels constrict.

Mild cases can be treated with slow, gentle rewarming at room temperature and pain medications. More severe cases may need surgery and medications to restore blood flow.

Q.
Is Cryotherapy Safe? The Medical Reality and Your Medically Approved Next Steps
A.
Cryotherapy can offer short-term relief for soreness and some pain when professionally supervised, but it is not risk-free, with documented harms like frostbite, nerve injury, blood pressure spikes, and breathing problems, and whole-body cryotherapy is not FDA approved to treat medical conditions. Before trying it, discuss your health history with a clinician, avoid it if you have heart or circulation disease, cold sensitivity, pregnancy, or neuropathy, use a reputable facility, keep sessions brief with protective gear, and seek urgent care for severe pain, persistent numbness, blistering, chest pain, or shortness of breath. There are several factors to consider; see below to understand more, including safer alternatives and step-by-step guidance on whether and how to proceed.
