They don't address the other parts of the foot being affected and do to address the real issue that is causing it to fall in the first place. (Tighten Achilles' tendon being a main culprit, bunions another though more often if you aren't a card carrying member of the pointed toe shoe brigade it's a side-effect of the fallen arch syndrome.)

But given the length of time you've been suffering as well as the swelling across the top of your foot and your ankle... have they taken an MRI yet? That's not typical of plantar fasciitis...discoloration and mild swelling on the bottom of your foot is normal and expected but it shouldn't be affecting the top of your foot and ankle. Sounds like you have a lot more going on than a simple flat foot, so if the doctor hasn't already ordered an MRI it might be time to find a new doctor, probably a sports medicine doctor.
