Plantar fasciitis (say PLAN-ter fash-ee-EYE-tus) is the most common cause of heel pain. The plantar fascia is the flat band of tissue (ligament) that connects your heel bone to your toes. It supports the arch of your foot. If you strain your plantar fascia, it gets weak, swollen, and irritated (inflamed). Then your heel or the bottom of your foot hurts when you stand or walk.
1 doctor agreed: Nerves: Most burning type of pain is caused by a nerve problem. Depending on the location of the pain on the bottom of the foot it may be caused by plantar fasciitis entrapping the nerve at the side & bottom of the heel. If at the level of the toes it could be a neuroma.
