You can perform several simple, preliminary checks at home to assess your peripheral blood circulation. First, perform the capillary refill test: firmly press down on your fingernail or toenail until it turns white, release it, and count how many seconds it takes for normal pink color to return (healthy refill takes less than two seconds). Second, check the temperature and color of your feet and hands; chronically ice-cold digits or pale, bluish skin discoloration can indicate poor blood flow. Third, check for lower leg swelling by pressing a finger against your shin; if an indentation remains, it indicates edema. You can verify findings with a medical professional.
