Well here I am again, a week later.  I know, I must commit and I will!  Did another 20 minute 'cardio' on the elliptical.  Beginning with a pulse of 88, I had a 10 minute pulse of 128, a 15 minute pulse of 136 and a 20 minute pulse of 155.  No resistance work yet. 

My left knee is bothering me; with aching pain every step, and an occasional sharp pain now and again.  I will be asking the 'orthopod' what can be done short of surgery.  When I had the 'vesco supplementation' done, they injected me with all three shots from the 'lateral' side (pain is medial) and I will explore the possibility of a 'redo' from the medial side.  And if that's not seen as possibly helpful, I'll ask what short term 'pain abatement' procedure might be administered  a day or two before our departure to Europe  (7/11) such as a 'corticosteroid' injection.    Having had many of those, I know it will only last a few weeks at best, but that might at least be sufficient to minimize the pain and make possible normal or near normal ambulation during our trip ...... stay tuned.
