I have plantar fasciitis and my feet continue to twitch and cramp in the arch , what can i do to stop them? it's 24/7, i've had new orthotics fitted.

Injection or surgery: Plantar fasciitis can resolve at some point on its own, but if it does not the options are primarily threefold: noninvasive things such as orthotics, stretches, therapy, ultrasound, etc.; or injection therapy usually with steroid or a variety of growth factors available; or surgery. There is really not too much else out there for it.
