Postherpetic Neuralgia
Lingering pain after shingles may indicate postherpetic neuralgia. Symptoms include burning pain, numbness, itching, and sensitivity to touch, caused by damaged nerve fibres that continue sending pain signals long after the rash heals.
Postherpetic Neuralgia (PHN) is a persistent and often debilitating nerve pain condition that develops as a complication of shingles. After the initial shingles rash disappears, some individuals continue to experience pain in the same area, a clear sign that the virus has caused lasting nerve damage. This article provides a detailed look into the common signs of PHN, explores its underlying causes, and explains how physiotherapy offers a powerful, non-invasive approach to managing pain and restoring daily function. Understanding this condition is the critical first step toward effective management and reclaiming your quality of life from chronic pain.
Key Signs and Symptoms of Postherpetic Neuralgia
The experience of PHN is typically confined to the area of the shingles outbreak. The primary issue is nerve pain lasting for three months or more after the rash has healed. Identifying the specific Postherpetic Neuralgia signs and symptoms is crucial for diagnosis and treatment.
Persistent Burning Pain
As the most common of all Postherpetic Neuralgia symptoms, patients describe a deep, constant burning, throbbing, or aching pain. The intensity can range from mild to severe, but its persistence is disruptive. This sensation originates from damaged nerve fibres sending continuous, exaggerated pain signals to the brain.
Extreme Sensitivity to Touch (Allodynia)
A hallmark symptom is allodynia, where even a light touch, like clothing or a bedsheet, causes intense pain. This hypersensitivity makes routine activities challenging and is one of the most distressing Symptoms of Postherpetic Neuralgia.
Sharp Pains, Itching, or Numbness
Beyond the constant burning, you might experience sporadic, sharp, jabbing pains, like electric shocks. Additionally, many people report persistent itching or numbness in the affected area, further signalling significant nerve disruption.
Muscle Weakness or Paralysis
While less common, the nerve damage from the shingles virus can affect motor nerves. If this occurs, it may lead to localized muscle weakness or, in rare cases, paralysis in the affected muscles, which requires immediate medical evaluation.
Primary Causes of Postherpetic Neuralgia
Understanding the Causes of Postherpetic Neuralgia is key. The condition is a direct consequence of nerve damage left behind by the shingles virus.
Reactivation of the Varicella-Zoster Virus
The root cause is the varicella-zoster virus (chickenpox virus). After a chickenpox infection, the virus lies dormant in nerve tissues. If it reactivates later in life, it causes shingles. PHN occurs when this shingles outbreak permanently damages these nerve fibres.
Nerve Fibre Damage and Scarring
During a shingles infection, the virus inflames a nerve pathway. In some individuals, this inflammation is severe enough to damage the nerve fibres. These damaged nerves then send chaotic and exaggerated pain signals to the brain that persist long after the rash has healed, causing the chronic pain of PHN.
Identified Risk Factors
Not everyone with shingles develops PHN. Key Reasons for Postherpetic Neuralgia risk include: Age (being over 50), Severity of Shingles (a severe rash and intense pain), and a Weakened Immune System.
How Physiotherapy Helps Manage Postherpetic Neuralgia Symptoms
While medication is common, physiotherapy offers vital, non-invasive management. At Physiotattva, we use targeted techniques to reduce pain, improve function, and empower you with self-management strategies for long-term relief.
Advanced Pain Management Techniques
We use modalities like Transcutaneous Electrical Nerve Stimulation (TENS) to block pain signals. We also prescribe gentle exercises that stimulate the body's natural painkillers (endorphins) for drug-free relief.
Nerve and Skin Desensitisation
To combat allodynia, therapists use desensitisation. This graded exposure to various textures and pressures helps retrain the nervous system to tolerate normal touch, reducing hypersensitivity over time.
Restoring Strength and Mobility
If PHN causes muscle weakness or inactivity, physical therapy is key. We design safe, customised programs with gentle stretching and strengthening to restore mobility and prevent muscle atrophy.
Functional and Pacing Education
Living with chronic pain requires new skills. We teach activity pacing, correct posture, and helpful ergonomics to avoid pain flare-ups, allowing you to maintain a fulfilling and active lifestyle.
Managing Postherpetic Neuralgia for Long-Term Relief at Physiotattva
Postherpetic Neuralgia can significantly affect comfort, mobility, and overall quality of life, but it is a condition that can be effectively managed with the right approach. By recognising key symptoms early, understanding the viral cause behind persistent nerve pain, and following a structured treatment plan, individuals can regain control over their health. Physiotherapy plays an important non-pharmacological role by helping reduce pain, improve nerve sensitivity, restore movement, and support long-term self-management. With a proactive, multi-disciplinary approach and consistent care, it is possible to minimise the impact of PHN and move toward a more comfortable, functional, and fulfilling daily life.

Frequently Asked Questions
What is postherpetic neuralgia symptoms defined as?
The defining symptom is nerve pain lasting three months or more in the location of a previous shingles rash. The primary postherpetic neuralgia symptoms include constant burning pain, extreme sensitivity to touch (allodynia), itching, numbness, and sharp, jabbing pains.
How is this nerve condition diagnosed?
Diagnosis relies on your medical history and a physical exam. A doctor confirms the condition by linking your characteristic nerve pain to a recent shingles outbreak in the same location. Extensive testing is rarely required for a definitive diagnosis.
Why is physiotherapy recommended for postherpetic neuralgia?
Physiotherapy addresses PHN’s functional problems. It uses desensitisation to retrain the nervous system, restores muscle strength lost to inactivity, and offers non-invasive pain relief like TENS. This approach empowers patients with self-management strategies for a more sustainable, holistic recovery.
Can postherpetic neuralgia be completely cured?
While no instant "cure" exists to reverse nerve damage, the condition is highly manageable. For many, symptoms fade over time. A combination of treatments, including medication and physiotherapy, can significantly reduce pain and improve quality of life, often leading to a full resolution of symptoms.
