Hi OP
I had an accident at work and badly damaged my lower spine. I found out in A&E that I was pregnant so couldn't have an x-ray.
I had a lot of pain throughout my pregnancy, which I was told was normal. I collapsed when I took my then 6-month old DS out of his highchair. Finally had a scan & they saw the damage. Like you, the steroid injection did nothing.
I was in an abusive marriage. I didn't want to have a general anaesthetic until my DS was older, so I took a decision to postpone surgery for as long as I could.
I was fitted for a custom corset with 4 steel rods inside - it really helped. Not the most glamorous article though!
I was being treated privately. My consultant sent me for an MRI every 6 months. When my DS was 4 years old, my consultant said if I didn't have surgery be paralysed 'soon'. My parents kindly looked after DS while I had a full spinal fusion (bone graft from my hip, titanium rods & screws) at L5/S1. The operation itself took around 7 hours. I knew as soon as I came round that it had worked - the post operative pain was nowhere near as bad as my old back pain.
I was in hospital for a week afterwards. The physios came round on the third day to get me up and about. They did that twice a day. I managed stairs on day 5.
Recovery was lots of walking and gentle stretching. I went back to swimming on around month 4 after surgery.
If your work has an occupational health department, I'd suggest letting them know about your situation. Mine were fab (this was a different employer to the place I had the accident). I went back to work on reduced hours 6 months after surgery.
Life now (16 years after surgery) - my back feels 'pinchy' in damp weather. I ache if I do too much (what is it with vacuuming?!). Heat packs work best. Nothing is as bad as the pre-surgery pain.
Good luck
