Beema - thankyou so much for posting that info and your video, I really appreciate it. Googling is a bad thing - TMI alot of the time and it helps so much more to speak with people who have some experience of it.

Lorirae - thanks also, it is pretty rare from what I've read. Hopefully mine will disappear as well. Often the bands show up with other abnormalities but mine is all clear so hoping for the best.

Smithy - thanks for your kind words - you are a treasure.

You have all been very reassuring, thanks so much for the support.
