This study suggests that glossodynia is a chronic pain disorder that causes psychosocial factors rather than neuropathic pain.
The cognitive characteristics of the glossodynia patients is catastrophizing, state anxiety, illness worry and state anger. They attention to bodily sensations and attribution of sensation to illness, these affect their emotional arousal and social response.
