Anyone else have chronic back spasm that renders you virtually useless? And it is always in the same spot?

If you have gone to a doctor for it what doctor did you see and what was the solution?

DH has a spot that has been bothering him for a very long time. He can reach over to get LO from from the car seat and that muscle will get pulled. And he will be in excruciating pain for days. He can reach for a plate the wrong way and the same same thing happens.

He's a very fit person that exercises, eats right and does core strengthening exercises. I am trying to get him to see the doctor about this because there must be an underlying issue.

Curious if other bees have insight.
