Yesterday the top of my foot cramped for a bit and then really hurt if i bent my toes (forwards). My brother (medical student) played with it for a bit and said it was probably something to do with the tendon (very useful!) Then I woke up this morning and if I walk or bend my toes the top hurts and kind of creaks (Like when knees sometimes creak.....you can feel it if you put your hand on top and I move my foot). Does anyone have any idea what's wrong with me? I took some painkillers and put some ibuprofen gel on it but it's still not comfortable. I don't know whether to keep it mobile or to keep it still and I'm supposed to be driving to a clarinet lesson soon.Any advice? x
