I don't know what's causing my shoulder deltoid pain.

 

 

My shoulder usually has no pain at all.

Raise your arms 90 degrees like in the picture

If I just lean back slightly, I feel pain in my deltoid area.

The part marked in blue in the photo

I've had these symptoms for over a week, but the pain doesn't go away.

 

Other movements are completely painless.

There is no pain at all, even when I sleep or am still.

However, as I wrote above, the pain only occurs with that movement.

 

I searched a lot about shoulder pain,

In my case, I couldn't find the cause.

 

Will it get better if I rest a bit?

Should I endure the pain and stretch with this movement?

Or maybe I should just rest without being stimulated

 

I've never done anything that put a strain on my shoulders.

 

If anyone has had a similar experience or knows anything about this, please let me know.
