I saw a dr say " esis have become highly overutilzd". I just had one b/c I have l3-5 degener. & 1.5 yrs of failed therapy help. What else is sugested?

This is true. Esi's have been overused, and worse even, some physicians will do them for any back pain instead of diagnosing facet verse muscular verse discogenic pain issues and this leads to useless treatments. I know this must be hard and frustrating for someone in pain. Would recommend therapy, but you obviously have tried that. Consider manual manipulation, acupuncture? Recommend finding good pain doc.
