Jeff Gordon has been suffering from back pain for a few years.
His Doctor zeroed in on the cause, a touch of arthritis, possible trauma from previous problem and aging.
On Monday, with this weeks' Coca Cola 600 approaching fast, Gordon had a minor procedure in which they give an injection of lidocaine or anti-inflammatory medication.
This procedure is called a facet block.
Gordon said he has experienced a bit of soreness, but is doing better and should be able to race the whole 600 miles pain free.
