Tinkling pain right shoulder blade.

I am quite in laptops and phone all the time and with a improper sitting position basically my back in a hunch position. Well this been done since 3 - 4 months I could sometime feel my right shoulder blade with some pinching pain. This used to go way after some time. But since last two weeks this pain is consistent and is in a particular place of right shoulder blade only. Eventually this led to extreme stiffness in my right side of neck and progressively went into right chest. Recently I made a doctor visit where he diagnosed it saying that it caused from anxiety. Well I am dealing with anxiety from last 4 yrs but it's not so chronic or extreme now that it used to be earlier. It's very rare. Well now I am confused whether should I go with his diagnosis or seek another treatment
