Please recommend a hospital that specializes in effective manual therapy.

Since a month or two ago, I have been experiencing frozen shoulder, and it has been slightly uncomfortable.

However, last week, suddenly, both shoulders hurt severely, and I couldn't even move.

Currently, I am taking joint painkillers and the pain has subsided.

I received advice that I need to undergo manual therapy.

However, I heard that the effectiveness of chiropractic treatment varies depending on the hospital you visit.

Please recommend a good place for chiropractic treatment in the Incheon area.
