Shingles Pain: A Guide to Understanding Postherpetic Neuralgia
What is Postherpetic Neuralgia?
Postherpetic neuralgia (PHN) is long-lasting pain that happens after a shingles rash goes away. Shingles is caused by the same virus that causes chickenpox. After you recover from chickenpox, the virus stays in your body but is not active. Years later, the virus can wake up and cause shingles.
When you have shingles, you get a painful rash. This rash typically resolves within a few weeks. But sometimes, the pain doesn't go away after the rash heals. This ongoing pain is called postherpetic neuralgia.
PHN happens when the shingles virus damages your nerves. The damaged nerves send pain signals to your brain even when there is no rash anymore. This can cause burning, stabbing, or throbbing pain that lasts for months or even years.
Who Gets Postherpetic Neuralgia?
Some people are more likely to get PHN after having shingles:
- People over 50 years old
- People who had severe shingles with a bad rash
- People who didn't get treatment for shingles right away
- People with health problems that weaken the immune system
- Women (slightly more than men)

Signs and Symptoms
The primary symptom of PHN is pain in the area where the shingles rash occurred. The pain may feel:
- Burning
- Sharp or stabbing
- Shooting
- Constant or coming and going
Many people with PHN find that even light touch, like clothing brushing against the skin, can cause severe pain. This happens because damaged nerves are extra sensitive.
Some people also feel:
- Tingling
- Numbness
- Itching
Ongoing pain can also cause emotional problems like:
- Feeling sad or depressed
- Worry and anxiety
- Trouble sleeping
- Feeling frustrated
Treatment Options
There is no single cure for PHN, but several treatments can help reduce pain:
Medications
- Pain relievers: Some antidepressants and anti-seizure drugs work well for nerve pain
- Skin treatments: Creams or patches with capsaicin or lidocaine can numb the painful area
- Strong pain medications: In severe cases, doctors might prescribe opioid pain relievers, but these are used carefully because they can be addictive
Other Treatments
- Physical therapy: Gentle exercises can help with pain and keep you moving
- Acupuncture: Some people find this helpful for pain relief
- Therapy: Talking with a counsellor can help you cope with chronic pain
- Nerve blocks: A doctor can inject medicine near nerves to block pain signals
- Electrical stimulation: Special devices can interrupt pain signals to your brain
Preventing Postherpetic Neuralgia
The best way to prevent PHN is to avoid getting shingles in the first place:
Get Vaccinated
The shingles vaccine is recommended for individuals 50 years of age and older. The vaccine called Shingrix works very well at preventing shingles and PHN. You need two shots, with the second one 2-6 months after the first.
Quick Treatment
If you think you have shingles, see a doctor right away. Starting antiviral medicine within 3 days of the rash appearing can reduce your chance of getting PHN.
Stay Healthy
Taking care of your overall health may help prevent shingles and PHN:
- Manage other health conditions.
- Reduce stress
- Eat healthy foods
- Exercise regularly

Living with Postherpetic Neuralgia
Living with ongoing pain can be hard, but these tips may help:
Pain Management
Follow your doctor's advice about medications and treatments. Keep track of what helps your pain and what makes it worse.
Daily Life Adjustments
- Wear loose, soft clothing over sensitive skin.
- Keep a regular sleep schedule.
- Learn stress-reduction techniques, such as deep breathing or meditation.
- Pace yourself and take breaks when needed.
Getting Support
- Talk to friends and family about what you're going through
- Consider joining a support group for people with chronic pain.
- See a mental health professional if you feel depressed or anxious.
Regular Check-ups
Continue to see your doctor to monitor your condition and adjust treatments as needed.
New Research and Future Treatments
Scientists are working on better ways to treat PHN:
- New medications that target nerve pain more effectively
- Gene therapy that might repair damaged nerves
- Improved electrical stimulation devices
- Better vaccines to prevent shingles
Some people may be eligible to participate in clinical trials testing new treatments. Ask your doctor if this option might be suitable for you.
Common Questions
- How long does postherpetic neuralgia last? PHN can last from a few months to several years. With treatment, most people experience gradual improvement over time.
- Can postherpetic neuralgia be cured? There's no quick cure, but treatments can manage the pain. Some people eventually recover completely.
- Is postherpetic neuralgia dangerous? It's not life-threatening, but the pain can seriously affect your quality of life.
- What's the best treatment? Treatment varies for each person. Your doctor will help you find what works best for you.
- Do I need to see a specialist? If your regular doctor's treatments aren't helping, you might need to see a pain specialist or neurologist.
Summary
Postherpetic neuralgia is a painful condition that can occur after a shingles infection. While it can be challenging to live with, many treatments can help reduce pain. The most effective approach is prevention through vaccination and prompt treatment of shingles.
If you're dealing with PHN, work closely with your doctor to find the best treatment plan. With proper care and support, you can effectively manage the pain and enhance your overall quality of life.
