My 32 year old daughter has cold, cold, cold, and sometimes purple hands and feet. She has fairly low blood pressure, but has not been told by a doctor that she has a real problem. Also, she has no periods and has not for five years. Her Doctor says that is OK too, Get chilblains in winter. I am worried. Do you think I should be? She hasn't been to Doctor for awhile because thinks all is same, and therefore fine.
