(Concern) Shoulder pain

While working at my job, I especially used my right arm a lot.

Is this how my body is breaking down now that I'm getting older?

The pain started to occur..

Right before my period or when I'm tired, I feel really heavy and sore as if something is placed on my shoulders... I don't think it's a frozen shoulder symptom though.

I used to go get acupuncture treatments for a while.

But it didn't get any better at all...

So, I'm thinking I should go to orthopedics.

Can this be improved with simple physical therapy?

If you just leave it alone, it will become even more difficult around the time of frozen shoulderㅠㅜ
