The chickenpox virus never leaves the body and it can come back as the painful rash of Shingles.
If you’ve had chickenpox, you can get Shingles at any time. It doesn’t matter how healthy you feel. Shingles can strike when you least expect it and can cause a blistering rash that may bring deep, penetrating pain.
The Shingles rash can last up to 30 days, and for most the pain lessens as the rash heals. But some people who develop Shingles experience long-term nerve pain that can last for months, even years.
