a few weeks ago after a run my foot had a strained aching feeling in it, on the outside part of the foot just in front of the ankle bone, and it went up my leg a little way. i rested it for a week and a half and it felt better, so i started running again. it felt fine during the run but the same sort of aching feeling returned after the run, but now mostly just around the foot, and it was not as bad. it feels fine when running, and directly after, but during the day when resting it seems to start again. does anyone know what this might be? should i take another week of rest?
