I have pain and coldness in my feet and some slight edema in the lower legs/ankles. I experience coldness in my hands as well but no pain. I have untreated high blood pressure and my Mom passed away at the age of 64 with the cause of death apparently from a heart attack. I am somewhat overweight but not obese. At work, I am generally sitting. I would describe my lifestyle as sedentary. My last blood test results (about 4 years ago) were normal with the exception of a vitamin D deficiency. What are the possible causes?
