Heel Pain

[nithy]

Greetings!
I have been told by a podiatrist in Texas that I have plantar fasciitis (PF) He recommended the following treatment:

stretches
physical therapy
custom orthotics for $795
3 shorts for each feet.

Are they the right treatment and the cost for orthotics is just very expensive. Can I order an online orthotics? Will the online orthotics have the same support for my PF or I have to cash out 795

Thank you in advance for sharing your experience
