BM good luck at the hospital, that is very brave and supportive of you, to go with your friend even though it will be hard for you.
I have a physio appt on tuesday, finally got my GP to refer me and it was quite quick. Last week I went back, after my back went again leaving me unable to walk well, went to work to be told by H&S officer that I should not be at work like this and to go get myself sorted! GP was surprised I had gone to work and promptly signed me off again. We discussed the fact that the disc tear might have got worse/another disc might have torn as the pain is worse/not going away and quality of life is being effected quite badly now. I was in a sorry state and I think he was quite
at how I was feeling/looking. He said he needed to think about what to do next and asked me to come back this week which I did. He has now, finally, referred me to the proper Pain Clinic at the hospital, where he said he has suggested in his referral letter they do another MRI, and said they can help me sort out my pain management better, including more local pain relief in the form of better injections than the caudal one, and other things. However the wait is going to be around 2 months or so.
He also changed my medication to tramadol, which I have fought as I have seen so many people struggle to manage on it/are out of it, but I was not doing great on codiene/cocodemol it just made me not very nice so I did not take it consistently. And the tramadol has little affect apart from making me a bit sleepy (but not groggy), but weirdly I cant sleep well on it! I feel fine on it, but it does not kick the pain as well as codiene, probably going to have to increase the dose. He has told me not to stop the pain meds, at all, not even one day, they need to build up.
I can probably work on them, so am going back on monday on a phased return as recommended by GP, but then go on annual leave for two weeks straight after! However, 2 days ago, i tidied up a bit, not very much, and I am in a lot of pain again. So, just can't see how I can go on like this long term without it seriously affecting my work. I have some worries about whether I will lose my job long term, but will not stress about it now.
mads I do luckily have some good friends around me for when DH goes away, and we have asked them to help out if I need them to. One of my closest friends has said she will come and stay with me if my back 'goes' badly. She is the godmother of the children so wants to spend time with them so will take them for a day i would think, some others are aware I might call on them if I am stuck. Have a plan in place. Which is mostly spending time on the beach/in NT gardens with a light picnic so the kids can run and I can sit, and visit my friends with armfuls of lovely food, which they can cook for us all 
Sorry for the epic post.
