I don’t know if you ever had this question fully answered, but in my humble opinion, I’m no doctor, but I don’t think you have social anxiety. Social anxiety is when you get panic attacks, and sometimes feel your head is swelling, or you’re sinking into the ground, simply when you’re surrounded by people. What you’re experiencing seems more like fear of being judged, like the “imaginary audience effect”. I suffer from this too. I think this, plus your claustrophobia, is what’s causing these social-anxiety-like fears.
