Sharp, burning pain that lasts weeks or months after a shingles rash is likely postherpetic neuralgia (PHN). It happens when the shingles virus damages nerves in the skin. The pain can be constant, come in sudden jolts, or feel like hot needles. For many people it’s the worst part of having shingles.
Shingles is caused by the same virus as chickenpox. If the virus wakes up in a nerve, it can inflame and scar that nerve. Older adults and people with severe, widespread shingles are more likely to get PHN. Getting treated quickly for shingles and getting vaccinated before you get shingles can cut the risk a lot.
Starting antiviral pills (like acyclovir, valacyclovir) within 72 hours of the rash reduces viral damage and may lower PHN risk. The Shingrix vaccine cuts shingles risk by about 90% in adults over 50 and also reduces the chance of PHN—ask your doctor about it if you haven’t had it yet.
There isn’t one perfect fix, but several options work well together. Topical treatments include lidocaine 5% patches for localized numbness/tingling and prescription capsaicin 8% patches for resistant cases. Oral medicines commonly used are gabapentin and pregabalin—these calm nerve signals. Doctors often start low and increase the dose until pain eases or side effects limit the dose.
Tricyclic antidepressants (amitriptyline, nortriptyline) and SNRIs like duloxetine also help many people. They can cause dry mouth, drowsiness, or dizziness—so older adults may need lower doses. Opioids are an option only for short-term severe pain and under close supervision because of addiction and side effects.
When meds don’t work, pain clinics offer nerve blocks, spinal cord stimulation, or other procedures. These are for persistent, severe pain and need evaluation by a pain specialist.
Non-drug actions matter: gentle exercise, good sleep, relaxation techniques, and cognitive-behavior strategies reduce how much pain ruins your day. Simple skin care—loose clothing, cool compresses, and avoiding rubbing the affected area—helps too.
Watch for warning signs: increasing redness, swelling, fever, or spreading skin breakdown needs urgent care. If pain is stopping you from eating, sleeping, or getting out of bed, see a doctor or pain specialist. Keep a log of pain intensity and what helps—that makes visits more useful.
Finally, be open with your clinician about side effects and driving or work safety when taking nerve medicines. Small dose changes or switching drugs often fix problems. PHN is frustrating, but with the right plan many people get meaningful relief and reclaim daily life.
