One of the most significant is postherpetic neuralgia. This occurs when nerve pain persists after the rash has healed. The pain may feel burning, stabbing, or electric, and even gentle contact with clothing can become uncomfortable.
Postherpetic neuralgia becomes more common with increasing age and may interfere with sleep, daily activities, and emotional well-being. Treatment can include certain prescription medicines designed to manage nerve pain.
Eye involvement is another serious concern. When shingles affects nerves around the eye, inflammation can damage structures needed for normal vision. Prompt assessment and appropriate treatment can help reduce the risk of lasting complications.
In less common cases, shingles can cause neurological problems, secondary bacterial skin infections, or other complications. People with weakened immune systems may experience more extensive disease.
The duration of recovery varies. Blisters generally crust over within several days to a few weeks, but pain or skin sensitivity can last longer. Persistent or worsening symptoms should be discussed with a healthcare professional rather than assumed to be a normal part of healing.
Older adults should be especially attentive to unusual nerve pain or a new blistering rash. Early evaluation is important because antiviral medication may shorten the illness and reduce the risk of complications in some patients.
It is equally important not to self-diagnose based on photographs circulating online. The appearance of a rash can offer clues, but a picture alone cannot determine the cause, severity, or appropriate treatment.

Chapter 5: How to Reduce Your Risk and Protect Your Health
There is no guaranteed way to prevent every case of shingles, but vaccination can substantially reduce the risk of developing the condition and its complications.
The recombinant shingles vaccine is recommended for eligible adults in many countries, particularly those aged 50 and older and certain adults with weakened immune systems. Recommendations, age thresholds, and availability vary by country, so individuals should consult a healthcare professional about eligibility and timing.
