In reply to climbingpixie:
I have had one but it was a long time ago. Thinking back, I think I felt fairly fragile immediately after i.e. that day.
I certainly went back to work the following day with no ill effects and don't think I did anything different from usual. I would have gone climbing I'm sure within the week. Not sure I was given any advice re training etc. However, I think the usual caveat applies - listen to your body.
Hope all goes well. x
