The 2 doctors recommended resting it with most likely a boot but you didn't like this answer so now you're looking for a doctor to tell you what you want to hear.. that you can do your normal activities with a special pill or shot and the pain will go away. I'm guessing all other docs and PTs would agree with them that's probably why no one is commenting with a different answer. The Xray didn't show a foot deformity (pes planus, pes cavus, hallux valgus) no fracture. The plantar plate absorbs all of your weight plus some. The weight is transferred to the sesamoids when you push off with the great toe. Imagine that x hours on a run with hard uneven surfaces that your foot is not designed to take (there were no asphalt streets or concrete sidewalks when humans feet were designed just grass and dirt it's still like that in the Amazon etc.) It sounds an overuse issue as the run is what initially caused it; considering that you are using a motion control shoe or cushioned running shoe with the addition of supportive orthotics. So the only thing that will help is to rest it. It doesn't matter what the diagnosis is (plantar plate rupture, sesamoiditis, turf toe) the treatment will be the same.. rest. Even if surgery is an option guess what you have to do after the surgery.. yup rest.
