could well be that the intensity and frequency of the exercises together with the orthotics is just a bit too much. After all this time the missing dorsiflexion wil not like being refound in 10 days. Why not give your physio a quick phone call for advice? She did the assessment after all. I would advise a patient to call if an intense or worrying reaction took place and then probably reduce either frequency or speed or intensity of some off/all off the exercises and let it calm down a bit.
