Plantar fasciitis is a condition that causes pain in the heel and bottom of the foot. It is caused by inflammation of the plantar fascia, a band of tissue that connects the heel bone to the toes. Common causes include overuse, obesity, and having a high arch or flat feet. Acupuncture is a form of traditional Chinese medicine that involves the insertion of thin needles into specific points on the body. It is effectively used as a treatment for plantar fasciitis to help reduce pain and inflammation.
