Shingles
Shingles: Early symptoms, the 72-hour golden window, and vaccines.
One-sided, band-like pain – that's all you need to recognize.
The varicella-zoster virus, which infects people in childhood, remains dormant in the body and reactivates along the nerves when the immune system weakens. While common in people over 50, it can also affect younger individuals.
- Pain, such as aching or throbbing, appears on one side of the body a few days before the rash, followed by the appearance of band-like blisters in that area.
- Antiviral medication should be started within 72 hours of the blister appearing to reduce pain and complications (neuralgia).
- If you experience unexplained pain on one side of your body accompanied by blisters, seek medical attention (dermatology or pain management clinic) immediately, even at night, and especially if it's a weekend.

If it's around the eyes or ears, it's an emergency.
If blisters appear on the forehead, around the eyes, or near the ears, it can lead to vision loss or facial paralysis, so immediate medical attention is necessary (requiring consultation with both an ophthalmologist and an otolaryngologist). This is a situation where you should go to the emergency room.
It can be prevented with a vaccine.
Vaccination against shingles is recommended for those aged 50 and over. The recently developed recombinant vaccine (administered in two doses) has a high prevention rate of over 90%. Costs and availability may vary by hospital, so please inquire beforehand. Even individuals who have previously had shingles can receive the vaccination to prevent recurrence.

Frequently asked questions
Can shingles be transmitted?
Shingles itself is not contagious, but it can spread chickenpox to people who have not had chickenpox (especially infants, pregnant women, and immunocompromised individuals) through the fluid in the blisters. Avoid contact until the blisters dry up, and cover the blistered area.
Could it be shingles even if there are no red blisters, just pain?
It is possible. In rare cases, there may be pain without blisters. If you experience unexplained and severe pain on one side of your body that persists, please seek medical attention.
