Diagnosis in Western Medicine:
If you are noticing that your hands and/or feet appear red and you are having painful burning sensations you should see your dermatologist and not your physician. Many times your dermatologist may be able to give a diagnosis that is based on the physical characteristics of your extremities or by the symptoms that you tell your dermatologist. If you are not experiencing erythromelalgia or a flare up at the time of your appointment the dermatologist may try to induce an episode of erythromelalgia by soaking a foot or hand in hot water. The dermatologist may also order blood tests, imaging scans, and neurological exams to look for signs of any underlying condition. To get the proper diagnosis it can take several months and you may have to consult many different specialists to find out what the problem is.
