My mom has plantar fasciitis as well - and she says that rolling her foot along the floor with a frozen water bottle helps her... she also says that two inch heals help her. I told her about the cold laser therapy that I received, and her doctor told her that it was quackery. She got steroid shots in her foot instead, but said that it didn't really help. I'm terrified of needles, so I was always unwilling to go the injection route.
