Not a long time!

A couple weeks, a few weeks!

Get the back fixed (remember, I said there was no way the disc would be stable yet?). Once Sally is certain your disc is fixed, and if you try the bike again and it hurts, then you will know you need to address bike fit and positioning issues.

Clearly something is pretty off with your bike fit or bike posture right now, because the bike is what really hurts the most. However, you can't address that until the disc is healed, because right now it's just confusing the issue.

When you can sit at work without pain, try the bike again.

It hasn't even been a week yet.

Keep chasing that disc back into place.

(if you had gashed your hand open with a kitchen cleaver, would you expect it to be healed up and functioning perfectly after 5 days?)
