2. Allergic purpura

clinical etiology and pathogenesis has no exact conclusion, but usually closely related to infection, genetics, immune disorders and other factors. In addition, unreasonable diet, emotional stress, mosquito bites, cold stimulation and other factors can also induce allergic purpura attack, so leg cold may cause allergic purpura.

3. Thrombocytopenic purpura is mainly

caused by immune system disorder, clinically infection, pregnancy, autoimmune diseases and so on can also induce the disease, but thrombocytopenia purpura is usually not affected by cold stimulation, so leg cold does not cause thrombocytopenia purpura.
