Looking for a good Korean medicine clinic or hospital for back pain in Gyeongju!

I often have back pain.
What causes back pain?
Of course, there are different reasons, but it hurts so much even if it's not a sprain and the sleeping position is a little uncomfortable.
Still, I'm curious as to why I experience back pain so frequently.
The disc keeps hurting constantly.
But when I get sick and then rest again
It gets better, then gets sick again, and repeats.

I went to the hospital and got a pain shot, but it was okay for a while, and then it started happening again.

I changed my mattress because they say it's good for back pain, but it's not that good.

If there is a hospital or oriental medicine clinic that you were satisfied with for back treatment in Gyeongju, please recommend it.
