Is it a heel spur, or plantar fasciitis? If the latter, what's causing it? In my case it was over pronation - a trip to a specialist sports podiatrist ended up in a set of custom insoles that killed months of pain stone dead within a fortnight. The doctor was useless; I got the podiatrist number from a physio who'd treated me earlier that year for an unrelated injury. The terms heel spur and plantar fasciitis are sometimes used to mean the same thing, which they aren't - if you ignore plantar fasciitis for too long, it may lead to formation of a heelspur.
