Neurological: Abnormal sensations of warmth, cold, tingling or numbness can indicate a problem with the neurological conduction system. It would be wise to seek a thorough evaluation to determine if there is an underlying medical problem causing this. A primary care Dr can do the initial assessment, but a Neurologist may be necessary to pinpoint the problem.
