Thank you, MadeInYorkshire. I've read your post , and others, with great interest. I'm sorry about your pain and
abdominal hernia. It sounds horrendous.
I'm not at all convinced that my spine is arthritic. I had COVID recently and couldn't do anything at all. Consequently I had no back pain whatsoever . Everyone knows that arthritis is still painful even when doing nothing.
I must just explain why I cannot take anti inflammatories, it's because I was on them for years (while waiting for replacement knee surgery) and they ruined my digestion to the extent that I must never take them again or risk an ulcer or worse.
Without further nagging my local surgery I don't know what else to do except just live with this . My pleas have got me nowhere. I tell myself that I'm too old anyway for treatment now and so must just endure.
But I wish you luck in finding an answer to your pain.
Ahh, shame about the anti-inflammatories, that's the big downside to those 
With my degenerative discs, there are probably some slipped out as well, and having lived with it for many years, the only thing I can do to relieve it is sit down! I already take Fentanyl to keep me 'comfortable', have Morphine for a crisis (like my bowel dying or a blockage) and take codeine at night, for pain and also because it helps with restless legs.
So, it looks as though yours could be the same problem, but as we've all said, only an MRI can really give you a proper diagnosis.
If it were me, the next time you go in, ask for a referral, if they refuse, ask the person you are speaking to why they are refusing, if you do not get a suitable response, ask for a copy of their 'Complaints Procedure'. Tell them you have been ? times and got nowhere, so you would like to formally make a complaint. You can always copy it in to your local Integrated Health Board as they are called now.
These people are obviously trying to sell a service but it tells you what can be done -

... and these people would be worth a call for advice too
