Aus – I’m 32 and for no reason have had bad back for 15 years and sounds like we’ve been through similar experience.
I didn’t do myself any favours as I was reluctant to give up martial arts and never stretch before/ after exercise etc.
However mid April I had my first injection and WOW, I had about 4 months of zero ache, pain, issues and had an amazing summer of riding. Month 5 I started feeling the odd short “reminder” I was really only masking the pain and for the last month I’m not back to where I was but am now daily feeling it. I’m booked in for my next one for mid Nov, NHS tell me you can have 2 per year.
Regarding the procedure, when I had it done my back was in a good state so had no issues and I felt nothing bar the numbing injection and an odd feeling of 35ml of fluid being pumped in (eeek). My mum who has the same has had one done and she said it hurt like crazy, was I lucky? Higher pain barrier? Ask late November when I’ve a second to compare against:-)
It changed my life, honestly. I became happier, enjoyed my hobbies more and even if they do hurt I had so much relief afterward I’d take it.
Final thing to say is you are supposed to do Pilates, swim, stretch etc to prolong good feeling and help strengthen and I didn’t really. This time I will and who knows, I may be able to sneeze in a cold morning without hurting for a winter season!
Good luck!
