Burning Mouth Syndrome (BMS) is a hot feeling or sensation which can affect your tongue, lips, palate, or areas all over your mouth. BMS is sometimes called ‘glossodynia'. You get this feeling when there are changes in the way the nerves in your mouth send messages to your brain - for example, about taste and temperature. When your brain doesn't understand these messages properly it can cause the feeling of pain or burning.

Hematology is the branch of medicine concerned with the study of blood and blood-forming tissues, including the bone marrow, and the diseases that affect them. It involves the diagnosis and treatment of a wide range of blood disorders, including anemias, leukemias, lymphomas, myelomas, and bleeding disorders.
