Shingles Support Group
Herpes zoster, colloquially known as shingles, is the reactivation of varicella zoster virus, leading to a crop of painful blisters over the area of a dermatome. It occurs very rarely in children and adults, but its incidence is high in the elderly (over 60), as well as in any age group of immunocompromised patients.
To answer your 2 questions:
1. How long might this (PHN) persist? It varies greatly, from one person to another, as to the length of recovery time for Postherpetic Neuralgia (PHN), or the nerve damage caused by the virus. The best way to approach this is to look at the statistics. There is a clear connection between the development of PHN and age. Those who experience a shingles outbreak over the age of 60 have a 40% chance of developing the condition while those under 60 have only a 10% chance. The length of PHN also appears to increase with increasing age. It has also been noted that those with a distinct prodromal stage (the tingling or burning sensations felt just before a shingles outbreak) had a higher incidence of PHN development. Women also seem to have a higher chance for developing PHN, but it may just be that they report symptoms more often than men. An important statistic to remember is that 99% of all cases of PHN come to complete resolution with 12 months, with the median between 2 to 3 months. There are some in this support group that are a part of the 1% that go beyond a year. So, always remember that statistics are on your mother's side.
2. Therapies that might hasten possible healing? I have read so many theories, but I am inclined to believe that a healthy lifestyle (exercise and nutritious diet) with PLENTY of rest will provide the most benefit. Also, extra vitamin B-12 seems to help somewhat. However, I think REST is the most important factor, so that your body can heal itself.
Good luck to your mom in her recovery.
