Shoulder blade pain

I heard that I have inflammation in my shoulder.
Even with treatment, the pain only goes away temporarily.
When I return home or work at the office
Suddenly, my shoulder started hurting like crazy.
My shoulder blade and back are very painful.

Where should I go to feel better??
Should I go to orthopedics?
Since there is no related department on the back side, please recommend one!
