I'm in the same boat. It sucks. Bi-lateral, going for just over a year now. Only seems to be affected when I try to do a long run or bump up my mileage. No running all winter, but telemark skied 180 days with no problem whatsoever. Started up training again this spring, low mileage weeks or shorter races (up to 12k), dull ache, but not the end of the world. Anything over 45 minutes and the pain rises on a direct curve. Signed up for 2 marathons this fall, went long a couple days ago to see what I was looking at (if it was even possible, w/ no meds masking), ran 17-18 miles all on trails for 2:25, wasn't pretty. Frustrating thing is rest of the body felt strong, but the groins were severely hurting. No health insurance, dreams of ultimately running ultras, i think the marathons are off the board, I have to get this addressed. Very helpful contacts and insight I've read so far, i'm in Northern Cal and Western NY parts of the year, if anyone has any ideas, willing to drive down to Philly this fall to take care of this. Again, thanks, good luck!
