How are heel spurs treated?

Many ways: Rest, compression, orthotics, surgical removal. Treatment will depend on the symptoms being caused.

Don't treat them: Heel spurs don't hurt. They are a byproduct of plantar fasciitis. If you reduce the inflammation of the fascia with support, antiinflammatories, stretching, icing, etc and continue to support with good shoes and possibly orthotics, there is little need to do anything to the spur. If all else fails, they can be removed, but it is the cutting of the attached plantar fascia that helps the pain.

Treat if painful: Heel spurs should only be taken out surgically if they are associated with chronic plantar fasciitis or symptomatic insertional Achilles tendonitis. Plantar calcaneal heel spurs rarely ever cause pain but can be taken out as a last line of treatment for plantar fasciitis. If the heel spurs do not bother you then you do not need to treat them.
