(Concern) My elbow has been hurting for over a year ㅠ

My left elbow has been hurting for over a year ㅠㅠ

Even after going to the hospital, getting injections, and taking medication, I still don't get better...

They say not to use your hands frequently, but how can I live without using my hands?

Even after taking medicine and getting an injection, I still felt a little better but...

It's very difficult and uncomfortable because I get hurt easily even with a little effort or overexertion.

Is it possible that inflammation is present even though there is no visible sign of it?
