What kind of shoes are you wearing? There are many kinds of shoes now that help with plantar fasciitis without having to buy custom orthotics. The last time I had a problem (now about 14 years ago) I saw an advertisement for Birkenstock shoes and testimonials said they helped a lot with plantar fasciitis or heal spurs due to the firm cork sole. I bought some, I’ve been wearing them since, my foot healed up and I’ve had no problems in at least 13 years. You don’t have to get Birkenstocks (though I love them and have about 60 pairs now because they never wear out),now there are other brands with the firm soles too. Just avoid soft soled shoes which actually allow the sole to stretch increasing the inflammation. For medication, seek an anti-inflammatory. For a diet, choose one that helps control inflammation.
