DEAR DOCTOR K: I have sciatica. Is it safe for me to ride a stationary bike for exercise?
DEAR READER: Sciatica is persistent pain felt along the sciatic nerve. This nerve runs from the lower back, down through the buttock and into the lower leg. Pain results when this nerve is compressed or injured. It most commonly results from inflammation, bone chips caused by arthritis, or a herniated ("slipped") disk in the lower spine.
