Knee Lubrication shot...?

[capecodbeach]

Finally seriously considering toget one of the Lubricating shots for my left knee. Not because of pain, the knee is just plain balky in the morning. Does not look swollen but sure feels that way? Actually gets freer after an hour or two. Not good for my golf game or for skiing. I am sure they will recommend replacement... like my wife is about to have. But I would be happy to simply have the left knee feel as good as the 75 year old right knee. Not urgently needed.... so I can schedule at my leisure. My real question: What is the down time I should expect? A week off from skiing? Two weeks off? I am sure someone on the forum must have gotten the lubricating shots. I would think the recovery is short but I am not sure I trust the times suggested in the sales pitch they give you.
BTW I just bought one of the programmable ice therapy machines for my wife's upcoming surgery. Amazing technology... I can set it for 10, 20, or 30 minute Cold therapy then set a rest period in minutes before the Cold therapy starts up again. All automatically. Sure beats shuttling ice packs.
