To be more specific, in my left foot my x-rays and MRI showed inflammation (tendonitis) right around the area where the Extensor Hallucis Longus and the Inferior Extensor Retinaculum overlap. The xrays actually show development of a bone spur right at that spot too. The skin right over that area has been red for months now, and the redness really doesn't go away, even after icing. I also have crepitus of the metatarsals, but only when the pain is at its worst. So I know what the culprit is in the left foot, as diagnosed by my podiatrist, and the right is presenting with the same scenario. I also tend to get lateral shin splints so I already do lots and lots of leg stretching before and after training. I think the orthotics have helped with the shin splints. When I have pain I try to avoid doing laps (our gym is small so running laps around it tends to tilt the body inwards and put unnatural stresses on the feet) squat kicks (which for me put my full body weight on the ball of one foot briefly). I'd try to take it easy outside of my twice weekly training sessions, but I'm a nursing student so on hospital days I'm on my feet all day, and on class days I walk a brisk hill and stair-filled mile to class and back to the parking lot.
