Again - thanks so much for all the info, researching, etc. I am thinking it is not a trauma (because there was none - unless there was something after a bottle of zin that I just don't recall) but the whole imbalance/ramping up too soon business. I am going to go to a PT bike racer friend after I see my doc.

Knot thanks for the avulsion details. Remote as it was, from the "they never do 100% O2 sat if they have a PE" kid, it was worth asking.

And I have been off anti-coags since Christmas. About a week or 2 before I got back on the bike.
