Cycling after back surgery

[tr7v8]

As per Sciatica thread on Health just had surgery on L5 to fix badly prolapsed disc. This was 11 days ago.
Surgeon removed two lumps one the size of a grape. He reckons on cycling after 2 weeks, but it certainly doesn't feel like it.
I started cycling last May after 30 years off a bike, a to get fit & also to lose some weight. Will be 60 in a couple of months.
Anyone any experience of this?

Thanks everybody for the advice, today is 2 weeks out of hospital & 4 days before that had the op. Came off the painkillers completely yesterday but that may be a bit soon!
