(Concern) My shoulder and back pain are getting worse and worse ㅠㅠ

I go to swimming lessons every morning.

I used to occasionally have shoulder pain before, but this time there seems to be no sign of improvement, and it keeps hurting more and more each day ㅠㅠ

Is it because of swimming, or is it because of my poor posture in general...

My hobby is lying down and watching dramas before bed... I think this might also be a cause. ㅠㅠ

While writing, I realize some bad habits come to mind ㅠㅠ

If the pain doesn't improve continuously, I should visit the hospital, right?

I'm thinking of trying to hold out with some patches.. ㅠㅠ

Should I go to the orthopedic department when I visit the hospital?

Would it be better to go to the pain medicine department?

I'm curious about how the treatment will proceed when I go to the hospital.
