Does herpes zoster still ache after scab

Herpes zoster may still present painful symptoms after scab because treatment for herpes zoster has cleared the chickenpox from the patient's body but has not completely repaired the nerves damaged by chickenpox. In addition to pain, the patient may feel repeated itching of the skin. Antiviral drugs should not be used arbitrarily at this time. Prolonged oral antiviral drugs can increase the burden on the kidneys and cause irreversible damage. The patient should take oral painkillers such as ibuprofen; drugs that promote nerve repair such as vitamin B12. It can also assist physical therapy, promote nerve repair, and relieve itching and pain as soon as possible.
