Chilblains usually go away on their own within a few weeks, but they can recur, especially in cold weather. The best way to prevent chilblains is to avoid cold temperatures and damp conditions. It is also important to keep the affected areas warm and to dress in layers to help keep the skin warm.
If chilblains are caused by an underlying medical condition, such as poor circulation, it is important to manage that condition to prevent recurrences.
If chilblains are not treated they can lead to complications such as infections, skin ulcers, and in rare cases, long-term skin damage, such as thickened or discolored skin.
It is important to see a healthcare provider for proper diagnosis and treatment, especially if the chilblains are recurrent or severe, or if there are other symptoms such as fever, fatigue or general malaise.
