LONG POND, Pa. -- Jeff Gordon anticipates he will have another injection at some point to relieve the pain in his lower back.
Surgery, however, is not an option.
"The option of surgery is really too invasive," Gordon said Friday at Pocono Raceway. "I don't necessarily think it's necessary. I might do another treatment of what I did a couple of weeks ago. We have to wait four to six weeks.
"They say [with] the second treatment, you usually have a lot better results than the first one."
Gordon first revealed his back pain may be more serious than first thought at Richmond, when he said an MRI exam revealed a touch of arthritis and other issues he would not discuss.
He had a facet block injection prior to the Coca-Cola 600 three weeks ago.
A facet block injection is performed to decrease the pain and inflammation in a facet joint or joints in the back or neck, or to confirm that the facet joint is the source of pain.
The injection typically is recommended for those who fail to respond to other conservative treatments. In some cases, if the problem is not corrected, surgery may be necessary.
"I really haven't seen any big effects from the first one, so I wasn't really thrilled about doing a second one," the four-time Sprint Cup champion said. "Anytime they talk about sticking needles in your back it's not something I'm looking forward to. It wasn't so bad though, and I'm certainly willing to give it a shot so we'll do that when the time's right and it fits the schedule.
"Until then, my focus is on the training and just stretching."
