I know I'm not crazy, Plunk. My doctor said some people feel something immediately but to expect maximum improvement in four to six weeks. For once I lucked out.
Like I said, I'm early stage, some doctors might just tell me to take Advil *shrug* I think my doctor's reasoning here is early intervention/slowed progression, plus without the pain you actually feel like
doing something and exercise helps OA. He said he's got one pt. that's been on the stuff for five years and is happy as a clam. Who knows what they could come up with in five or more years?

It was less than ten years ago Synvisc was a series of three shots and now it's one big blast.
I'm actually pretty familiar with hyaluronic acid, I was taking it as a dietary supplement last year (didn't do shit that I could tell, but it makes a great moisturizer when applied topically).
