Summary
Brief summary
Vitamin D is able to treat viral infections. As such a high potency vitamin D cream could also be useful in the treatment of the acute viral reactivation associated with acute herpes zoster. Inflammation of cells called glial and schwann cells which surround nerves in our nervous system are also known to have a major influence on pain. Drugs that reduce inflammation in these cells are now being trialled in a number of pain conditions. One drug/ natural supplement that offers particular promise is vitamin D. Because post herpetic neuralgia responds to a number of topical medications, vitamin D is being trialled in a topical form. If a vitamin D cream was an effective treatment for acute post herpetic neuralgia this would be a major treatment advance as it could provide a simple cost effective treatment option with minimal side effects.
