Thanks everyone. I did have a sports hernia a few years ago but I think I am fully recovered from that. I completely agree with the idea that I am race walking - when I see videos of me running I look like I am walking in fast-forward video. My podiatrist told me that my foot pain is causing me to take shorter strides to reduce impact on the feet which is causing the rest of my legs to get sore which is further exacerbating the short stride problem. But I question which is the cause and which is the effect.
About my hips - the doc I saw when I had the stress fracture concluded that I have pistol grip cam impingement in my hip sockets which somewhat limits my range of motion.
I am visiting the POD again this week so I will have some good questions based on this discussion. Thanks!
