Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Hypoalgesia
Reduced sensitivity to painful stimuli, making it difficult to feel cuts, burns, or injuries.
Seek immediate care if you notice wounds or injuries you did not feel occur, as this increases risk of infection
Complete sensory loss
Total loss of sensation in affected areas, including inability to feel touch, pain, or temperature.
Seek immediate medical attention as this significantly increases risk of unnoticed injuries and infections
Allodynia
(neurologic)Painful sensation in response to stimuli that normally would not cause pain, such as light touch or gentle pressure.
Frequency: 70-80% of patients
Hyperalgesia
(neurologic)Heightened sensitivity to painful stimuli, where painful sensations feel more intense than usual.
Frequency: 65-75% of patients
Paresthesia
(neurologic)Abnormal tingling, pins and needles, or numbness sensations, often described as prickling or burning.
Frequency: 60-70% of patients
Dysesthesia
(neurologic)Unpleasant, abnormal sensations that may feel like crawling, itching, or electric shocks on the skin.
Frequency: 40-50% of patients
Hyperesthesia
(neurologic)Exaggerated sensitivity to sensory stimuli, where even mild touch, sound, or light feels overwhelming.
Frequency: 15-20% of patients
Thermal dysregulation
(constitutional)Abnormal perception of temperature, where hot or cold sensations feel distorted or exaggerated.
Frequency: 35-45% of patients
Tactile defensiveness
(dermatologic)Intense aversion to certain textures or types of touch, causing discomfort or pain from fabrics, materials, or light contact.
Frequency: 10-15% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.

Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Sensory Re-education Therapy
Targeted exercises and stimulation techniques designed to restore normal sensory processing and discrimination. Treatment involves graded sensory exposure to various textures, temperatures, and stimuli.
Neuropathic Pain Management
Pharmacological approach using nerve-stabilizing medications to address sensory abnormalities and associated discomfort. Treatment focuses on modulating sensory pathway function.
Additional treatment options
Environmental Modification
Implementation of protective measures and environmental adaptations to compensate for sensory deficits. Includes use of protective footwear and avoiding extreme temperatures.
lifestyleAcupuncture for Sensory Normalization
Traditional acupuncture techniques targeting sensory meridians to potentially improve exteroceptive sensation. May help modulate nervous system responses.
complementaryNeurological Assessment
Regular comprehensive neurological evaluation to monitor sensory function progression and guide treatment adjustments. Includes quantitative sensory testing.
