If you have persistent or frequent chills in your lower legs regardless of the weather outside or the temperature around you, and they do not improve with treatment at home, there may be an underlying disease or condition that requires treatment. Medical attention should be sought to identify the cause.
Treating the underlying condition is the best way to relieve coldness in the lower legs. If you have other symptoms, such as discoloured fingers or toes, difficulty breathing or pain in your hands or legs, seek medical attention.
