Talk to Chiropractor on Back Pain, Chiropractor

I have had back pain which starts in the middle right of the back (T8 vertebra) and goes into the right ribs. The pain is there for around 10 months now and starts only when I am seated in a chair for a while such as while working or while having dinner. Easy chairs and bed do not cause any issues. A spinal doctor did MRI and it was clear.

I have started treatment with a chiropractor recently. I have now completed 2 sessions without any change in my pain.

The chiro first applies electric signals for pain management for 10 minutes, then a percussor on the whole back for a couple of minutes, followed by spinal adjustment while I lay on my back and on my sides.

I just need to know that based on what I have shared above and with no improvement in symptoms, should I continue the remaining sessions or should I see a physiotherapist?

There is no other chiropractor available in my city.

Many thanks for your guidance in advance.
