(Concern) Chiropractic Clinic for Back Pain

I often experience lower back pain. When that happens, I take painkillers or, if it doesn't improve, I go to the hospital. Usually, at the hospital, they perform physical therapy and prescribe painkillers and muscle relaxants.

I have to go for several days, and taking medication makes my stomach upset, so it's difficultㅠ

I have never been to a Korean medicine clinic or traditional Korean hospital, so I’ve always been worried... When I go for back pain, what kind of acupuncture and treatments do they provide? Do they work immediately... Do I need to go regularly... I’m curious.
