My groin/leg thing is still an issue, which is sort of amazing. Or maybe not so amazing, since I give it a rest for a day or two and then whale on it again with a race or hard workout.
I’m reminded of when I was training for my very first marathon, a five month period in which I had nonstop shinsplints (or, rather, a wandering shinsplint) for four of those months. I just took ibuprofen constantly, sometimes ran in mild to moderate pain, and the problem went away.
In a way, this is not as bad because it doesn’t actually hurt while I run. It just hurts first thing in the morning after a hard run the day before, and only when I do certain things (like go up or down stairs, lift my leg over the side of the tub, etc.)
I could be an alarmist and take some days off, but I’m not inclined to. I just have a feeling it will go away on its own eventually, as every other quasi-injury has. Damned annoying, though.

It was a sudden injury, so you’d think it’s not a stress fracture or osteitis pubis…

Might be worth getting checked out by a good sports doctor (not easy to find a good one!), or a physiotherapist.
Interesting story about the food cravings. I think salt could be an ‘auto craving’ – especially when running in 30+C.
I hope the injury cat soon better.
Perhaps the cold wether is not so good for the legs?.
But i think your feelings are good and take a litle rest.
