Herpes zoster neuralgia is a type of neuralgia that frequently affects the elderly. It often develops due to fatigue, lack of sleep or the use of immunosuppressive drugs. The pain is very intense. Some patients describe it as electric shock, burning, or pins-and-needles skin pain, along with herpes zoster, which can seriously affect the health of the elderly. Patients should be especially reminded here that the disease is both a skin lesion and a neurological lesion. The acute phase of herpes zoster is accompanied by neurological damage. The herpes zoster skin lesions eventually heal, while the residual nerve damage remains as post-herpetic neuralgia. This post-herpetic neuralgia is very painful, often lasting months, years, or even a lifetime, and can be very difficult to treat. What can be done to prevent postherpetic neuralgia? First, it is important to prevent the occurrence of shingles. This includes avoiding cold, avoiding fatigue, getting enough sleep, and having balanced nutrition. Secondly, patients suffering from shingles must visit a pain department promptly. Treatment of the acute phase of shingles is critical. It is important to give the first antiviral and analgesic treatment and nerve block treatment. Nerve block therapy is very effective in pain relief and in preventing postherpetic neuralgia. With the use of nerve stimulator and ultrasound-guided technology, its accuracy and safety are increasing. Again, we highly recommend it to our patients and friends. Finally, to answer the question of many patients, what to do after getting herpes zoster neuralgia. The main thing is to pay attention to rest, sleep well, no special taboos, a balanced diet and avoid spicy food.
