Should I suspect a shoulder condition due to pain in the left trapezius muscle?

I'm very worried because I feel severe pain on the left trapezius muscle side.

I'm wondering if this pain, which seems to spread to my shoulder, could possibly be related to a shoulder problem.

I heard that pain in the left trapezius muscle might be related to shoulder conditions, but I'm not sure what symptoms might appear.

 

 

What tests should be done if the pain persists?

I also want to know what other treatment options are available.

 

What other symptoms, besides pain, can accompany shoulder disorders?

And I am also curious about what should be done to manage or prevent this.

 

 

If anyone has had a similar experience or has related information, please kindly offer your advice.

I'm feeling anxious and contemplating various things, so I would really appreciate any information that might be of even the slightest help.

 

Thank you!
