OUCHIE!!
You know that one of the first tests is to drag a pencil across the ground in front of you -- as soon as those toes go to pull it, "Damn!"
Which is exactly the motion of skating!
That's the bad news, of course. (And no news to you, no doubt.)
Have you rolled your ass on a tennis ball? That really works nicely.
In road races (in ancient times, for me), I would pound a knuckle into my butt, right where it hurt most -- that might buy me 5-10 minutes of relief.
But it was laying on my back, doing those (pretty standard) piriformis stretches *ferociously* -- for 20 minutes at a time -- that finally loosened me up. And it took *months*, not weeks.
So, be patient, and do *longest* what hurts the most to do. That's usually Bad Cliché advice, but is totally good with Pain-In-The-Ass Syndrome.
I would advise, too, to go for IT-Band stretches, as it's really your whole Lower Unit that's tight -- which means that tight quads will be solved by loosening everything connected right up to your Iliac Crest (your belt line). Whacky, but way good and true.
BEST WISHES.
