In the last couple of weeks there have been a lot of very old threads with new answers, ranging in age from 7 months to 2 years and more. Occasionally there is a good reason for adding to an old thread but when it was a question relating to treatment at the time or something current it can be a bit confusing and people may be upset when they don't get a reply.
So please have a look at how old it is - it does tell you how long it is since the thread was created or the most recent reply written.
