My back issues started in 2016. I had Physio, painkillers and a lot of time off sick.
At the worst point I was catheterised, a good day was washing my own feet.
MRI showed 2 prolapsed discs
I had an xray guided injection (approx 12 months later) which worked an absolute charm for 48 hours, then nothing.
Just over 12 months ago I had surgery. It was like someone flicking a switch, the pain was gone and now I’m back on my bike.
Thats not to say it wont work for you, but in my case it did nowt.
