Hay!
Just going to be very brief, if you want some more information just ask and I can take some more time in the next few days to explain your condition and some treatments/advice.
Yes, go back to the physio who gave you the orthotics, he/she seems to know foot mechanics well enough. A good physio can greatly help someone with PF. The last thing you want is for PF to become a chronic condition, it can become quite a limiting factor in everything you do, I have seen this a few times in ex-army/Dep Vet Affairs clients.
Book in with your physio asap and they can explain why/what they can do to helpIf you feel like he/she didn't explain anything properly or you feel like treatment is not helping, feel free to send me a private message or repost here and let me know, and I will take the time to be a bit more expansive.
Continue with the anti-inflams too, they have shown to compliment our treatment fairly well with most clients w/ PF.
If you read this article, it provides you with ALOT of information on effective treatments.I highly suggest wading your way through it and researching anything you are not sure of as you go.
