Why does shingles still hurt after the blisters have crusted over?
Disease description:
I am thirty-eight years old this year. I was recently diagnosed with herpes zoster. Although the lesions have now crusted over following treatment, I still experience pain. Why does herpes zoster still hurt after crusting?

Dr. Wang Xiaoyan
The reasons for still feeling pain after shingles blisters have crusted over may include:
1. Nerves have not fully recovered: Shingles is caused by infection with the varicella-zoster virus, which can damage nerves and lead to neuropathic pain. Although the skin has crusted over, the nerve repair process may be slow, so pain may still be present.
2. Inflammation or infection: Improper wound care during the crusting process may lead to bacterial infection or a persistent inflammatory response, thereby increasing pain.
3. Residual virus: A small amount of virus may remain in the body, continuing to irritate nerves or skin and causing pain.
To relieve pain, patients can take antiviral medications, nerve-nourishing drugs, and analgesics under a doctor's guidance. Additionally, maintaining healthy lifestyle habits and proper skin care can help promote recovery.
