Delayed healing of injuries of the feet
This goes along with the unexplained cold feet. Injuries need blood to heal. If the blood is not flowing there, or not flowing there sufficiently, these injuries will heal slowly or not at all. If you notice that injuries in your feet or lower legs are not healing as they should talk to your doctor.
Heart palpitations
Truthfully, anytime you notice changes in your heart rate, you should see your doctor. When your heart beat suddenly becomes noticeable, heart palpitations could be a sign that blood is not flowing the way it should. This can feel like a heart pounding, fluttering, or beating irregularly. It will usually last for just a few seconds or minutes. It is possible that you will feel these sensations in your neck or throat, as well.
