DEAR DOCTOR K: I have terrible sciatica pain from a slipped disk, but I've hesitated to take steroid pills. What do you think about this treatment?
DEAR READER: Your spine is essentially a column of interlocking bones called vertebrae. A disk tucked in between each pair of vertebrae acts as a shock-absorbing cushion. Sciatica often occurs when a disk becomes displaced (herniated) in the lower spine and injures or compresses the sciatic nerve. This causes sciatica, a severe, shooting pain, tingling, numbness or weakness that runs from your lower back through the buttock and into the lower leg. (At the end of this post, I've put an illustration showing common causes of sciatica.)
