Thank you all for your comments.
The BMB (note the jargon) went well yesterday, but I was surprised when my next appointment was made for 24 June, seems a long time to wait for the next step.
I am going to Queens Hospital, Burton on Trent by the way.
Currently I am most concerned about my eyesight which has been badly affected (it was why I went to opticians in the first place); and the back pain for which I was given some pain killing patches yesterday.
Now waiting impatiently.
Thanks again
