All rapid responses
Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
May I thank Ting, Ghosh and Ghosh for an eminently readable article? A couple of points.
1. CYANOCOBALAMIN by injection.
It was, once, reputed to be very effective in reducing the associated radicular pain.
Has it been consigned to the dustbin of history? No adverse effects were ever reported.
2. PERIOD OF INFECTIVITY.
In CHICKEN POX, - it was said that a week after the first crop of vesicles appear, the patient is non-infective. It was thought that the body inactivated the virus. If that “ thought” is correct, then I wouldlike to know how the virus hiding in the dorsal horns manages to travel down the axons to the terminals and creates pathology ( vesicles) there in the skin.
Thank you

Having had shingles in V1 I don't recommend capsaicin cream. It dried to a flaky papery texture, making my forehead look even worse, and making a message of my hair.
Gabapentin soothed my post-herpetic neuralgia but made me feel spaced out and remote; other people noticed it too. Pregabalin, recommended by NICE, was a million times better

Re: Herpes zoster ophthalmicus
Thanks to the authors for this readable and interesting article.
From a General Practice perspective I wish to raise a couple of areas which would benefit from clarity.
The authors describe Hutchinson’s sign as being rash involving the tip, side or root of the nose, however I was taught Hutchinson’s sign is vesicles on the tip of the nose - ie the distribution of nasociliary nerve.

The authors recommend ophthalmology referral for patients with any ocular symptoms but do not comment on whether referral required for all with Hutchinson’s sign. This information would be helpful for Primary Care and Emergency Medicine colleagues.
