Simon, you haven't mentioned what kind of treatment. Surgery or you two watching it closely?

I have 6 congenital defects in my lumbar spine, had a double lum-lam and a spinal stenosis cleared out of one of the lumbar vertebrae.

I know how surgeons can suggest a wait-an-see approach in some cases, and the downside of that approach is you need to be very careful of bumping around, because that not only hurts, but it causes the disc to bulge further. I'm sure your surgeon told you that after surgery your back will never be quite the same. So there is a big decision there.

After my surgery it took about 2 years for things to settle back to near normal. During that time cycling was iffy. If I maintained absolute perfect form I was fine, but hit a bump or move just a bit out of proper cycling form and it really hurt.

Decades later I'm riding with no pain. Bike doesn't matter.
