A dulled, unpleasant, or altered feeling that exists without an obvious stimulus: One example of an abnormal sensation is when a person has a burning feeling when there is no heat involved.

Abnormal sensations can result from damage to, or a pressure on, certain nerve pathways.

The most common types of abnormal sensations are tinnitus or numbness and/or feelings as if one is stuck with pins and needles. Sometimes such a sensation is combined with pain and even with a feeling of being very cold or a feeling of severe burning.
