Hyperesthesia

Hyperesthesia is a condition where your skin becomes extremely sensitive to touch, temperature, or other sensations. Normal stimuli that shouldn't cause discomfort - like clothing touching your skin, a gentle breeze, or bed sheets - can feel intensely uncomfortable or even painful. This heightened sensitivity occurs when nerves become overactive or the nervous system incorrectly amplifies normal sensations. It gained recognition during the COVID-19 pandemic as a distinctive symptom in some patients.

Hyperesthesia is invisible - the affected skin typically appears completely normal:

• No rash, redness, or visible skin changes
• Skin looks and feels normal to others examining it
• You may notice yourself pulling away from touch or avoiding contact
• Difficulty wearing certain clothes or fabrics
• Avoiding activities that involve skin contact

Hyperesthesia can affect:

• Generalized: Entire body surface, particularly trunk and back
• Abdomen and back: Most commonly reported areas, especially in COVID-19 cases
• Arms and legs: May feel like burning or electric sensations
• Localized areas: Following nerve distributions after shingles or injury
• Variable patterns: May shift location or intensity throughout the day

Hyperesthesia often occurs with:

• Burning or stinging sensations without visible cause
• Feeling like sunburn without sun exposure
• Electric shock-like sensations
• Extreme discomfort from clothing, especially tight-fitting garments
• Relief from warm baths or showers
• Difficulty sleeping due to sheet contact
• Anxiety about being touched

Seek medical attention for:

• New onset hyperesthesia, especially with fever or other symptoms
• Sensitivity lasting more than a few days
• Hyperesthesia following COVID-19 or other infections
• Pain severe enough to interfere with daily activities
• Associated weakness, numbness, or other neurological symptoms
• Hyperesthesia in a specific pattern suggesting nerve damage
• No improvement with simple comfort measures
