Why does shingles pain go on and on? After the rash goes away, some people may be left with long lasting pain called post-herpetic neuralgia or PHN. The pain is felt in the same area where the rash had been. For some people, PHN is the longest lasting and worst part of shingles. The pain can make some people feel weak and unable to do things they usually enjoy. Those who have had PHN say the pain is sharp, throbbing, or stabbing. Their skin is so sensitive they can't bear to wear even soft, light clothing. People who have PHN call it a pain that won't go away.
The older you are when you get shingles, the greater your chance of developing PHN. This pain can last for weeks, months, or even years. "I've had post-herpetic neuralgia for nine months," said Pete, an 80-year-old man. "I've lost 20 pounds. I can't find anything that helps with the pain."
The PHN pain can cause depression, anxiety, sleeplessness, and weight loss. Some people with PHN find it hard to go about their daily activities like dressing, cooking, and eating. Talk to your doctor if you have any of these problems. There are medicines that may help. Usually PHN will get better over time.
Other Complications From Shingles
In some cases, blisters can become infected. Scarring of the skin may result. Your doctor can prescribe an antibiotic treatment. Keep the area clean, and try not to scratch!
There are other problems to watch for. If blisters occur near or in the eye, lasting eye damage or blindness may result. This can be very serious. See an eye doctor right away.
Other problems may include hearing loss or a brief paralysis of the face. In a small number of cases, swelling of the brain (encephalitis) can occur. It's very important to go to the doctor as soon as possible— especially if you have blisters on your face.
