Neuropathy Symptoms: Recognizing Pain, Numbness, Weakness, and When to Seek Help

Peripheral neuropathy affects nerves outside the brain and spinal cord. Symptoms depend on fiber type (sensory, motor, autonomic) and distribution.

Sensory Symptoms

• Pain: Burning, aching, sharp, stabbing, electric-shock-like. Often worse at night.
• Numbness: Reduced or absent sensation, often "stocking-glove" distribution (feet/hands).
• Paresthesia: Tingling, pins-and-needles, crawling sensation (formication).
• Dysesthesia: Unpleasant abnormal sensations (e.g., cold felt as burning).
• Allodynia: Pain from non-painful stimuli (light touch, clothing).

Motor Symptoms

• Weakness (distal > proximal): foot drop, difficulty gripping.
• Muscle wasting (thenar eminence, interossei, tibialis anterior).
• Cramps, fasciculations.
• Loss of deep tendon reflexes (ankle jerk first).

Autonomic Symptoms

• Orthostatic hypotension (dizziness on standing).
• Gastroparesis (nausea, bloating, early satiety).
• Constipation/diarrhea.
• Urinary retention/incontinence.
• Erectile dysfunction.
• Anhidrosis (reduced sweating) or hyperhidrosis.
• Pupillary abnormalities.

Balance & Coordination

• Sensory ataxia (worse in dark/eyes closed).
• Unsteady gait, falls.

When to See a Doctor

Seek evaluation for:

• Progressive or asymmetric symptoms.
• Weakness, falls, or functional decline.
• Autonomic symptoms (syncope, GI/GU dysfunction).
• Pain interfering with sleep or function.
• Associated systemic symptoms (weight loss, fever, rash).

Early diagnosis (EMG/NCS, labs, imaging) can identify treatable causes (diabetes, B12 deficiency, autoimmune, compressive).
