Sorry to hear about your injury. I wish you the best!
As always, it’s advisable to work with your doctors and those you trust, as each person’s body is unique. For what it’s worth, a family member of mine has multiple herniated, bulging, and/or crushed discs in their back. It’s caused decades of problems and for years kept this person off their bike. What finally worked for them was finding a bike with a very specific geometry that aligned their back in a way they could pedal without inflicting excess pressure on the injured sections of their spine.
It took months of trying every bike we could get our hands on and making all sorts of modifications to stack height, reach, pedal position, saddle, etc. In the end, though, one was a clear winner and now this family member is back to riding almost daily.
