When you are sitting, your toes or feet may turn slightly
blue because of decreased blood flow. The color will usually return to normal
when you move your legs and get blood moving into them again.
your toes or feet become pale or blue and the color does not rapidly return to
normal, blood circulation to your toes or feet might be decreased. These
symptoms may be more serious if other changes occur to your lower legs and
feet, such as thinning of the skin, sores that don't heal, development of pain,
or loss of hair.
Because dizziness can involve so many parts of the body -- the ears, brain, or heart, to name a few -- your doctor will probably take a careful history of your symptoms, do a brief exam, and make a proper referral to a specialist if necessary.
Make sure you describe the sensation you feel thoroughly, since dizziness can be many things to many people.
