Again, since poor circulation comes with its own symptoms, you might have a reason to see a doctor if you have any of the symptoms appear. Numbness and the feeling that your legs are always cold is a big first sign that your legs and feet aren’t getting enough oxygen and nutrients from your blood. Toenails would thicken if you aren’t getting enough blood flow to your legs because the toenails are living organisms made from keratinized hair and need that circulation in the nail bed to form properly. If you notice that the hair on your legs is no longer growing or that it is falling out, you might have a circulation issue. This is because hair also needs that blood flow to grow, much like your toenails. Poor circulation can lead to swelling also, making the skin on the legs shiny and red if they hang down below where the blood comes from. Elevating your feet may alleviate swelling and pain.
If you have poor circulation in your legs, there are several issues that you need to look out for once you realize what’s going on. If you get a wound on your leg, even an ant bite, it won’t heal properly. Poor circulation can cause ulceration, which is the appearance of sores on their own, or can cause massive infections in your feet and legs provided that there’s not enough white blood cells to carry the damaged cells away from the wound. Coupled with the numbness might cause a person to not feel any pain or feel that there is an infection at all. The numbness is caused by lack of oxygen – there is no blood to carry the oxygen to the limbs in question so there is no feeling in them. Numbness can be extremely dangerous because if you get hurt, those wounds that are so prone to infection and won’t heal properly can occur and the owner of the limb won’t even notice. Of course, another problem with poor circulation, is that eventually the limb is going to get some circulation and eventually “wake up.” This means all the pain that is associated with a waking limb can still affect a person with poor circulation.
All of these symptoms, especially ones that deal with infection need to be addressed by a physician at any point that they occur. These symptoms and issues can be a sign of a more debilitating issue and could be life threatening if left to coagulate. Do not attempt to treat any of these issues yourself until you have seen a doctor for rounds of medicine or treatment by other professionals.
