It seems to be suffering from peripheral neuropathy of some sort. Peripheral neuropathies are caused by injury and inflammation or compression of the nerves located outside the brain and spinal cord. Metabolic diseases (eg diabetes ) , endocrine problems (eg A thyroid disease ) , exposure to toxic substances ( Alcohol, heavy metals, drugs , etc. . ) , Autoimmune diseases ( lupus , rheumatoid arthritis, etc. . ) , nutritional disorders (vitamin B12, or vitamin B6 toxicity ) , impingement syndromes (eg carpal or cubital tunnel) and cancer are some of the causative peripheral neuropathies . Carpal tunnel syndrome is a common cause of abnormal sensations in the hands (usually numbness in the thumb and index finger ) . The carpal tunnel syndrome worsens at night because people tend to bend their wrists during sleep , which causes a lot of pressure on the median which is what provides the sensitivity and muscle control on one side of the hand nerve. If the burning sensation or itching involves the whole hand , the problem would be different. Without more information without a face- examination is impossible to determine the cause of your symptoms. If you have not already made ​​an appointment with your doctor to suggest it does.
