7. Postherpetic Neuralgia
Chickenpox is a disease that is caused by the varicella-zoster virus. The disease is not nearly as common as it used to be thanks to vaccinations that have made it all but extinct in some parts of the world. A lot of people still alive have had chickenpox, however, because the vaccine was not available when they were younger.
The virus will remain in the host and will usually remain dormant. It will sometimes be reactivated, however, causing a condition known as shingles. Shingles is very painful for the patient and will often cause postherpetic neuralgia. This condition damages the nerves and can cause a great deal of pain for the patient.
