If not claustrophobia, then what?

Question

I was wondering if anyone knew a specific name for whatever I experience that is somewhat related to being closed in, but isn't claustrophobia?

It's more so the feeling I get of not being able to breath, usually occurring within a small, closed space. My face gets hot, my heart starts to pump faster, and I have shortness of breath.

This sometimes can just occur when my face is too close to a wall and not in the open when I'm trying to sleep.

Answer 1

claustrophobia or panic attacks .

Answer 2

That sounds like claustrophobia to me,  

Answer 3

You are suffering panic attacks.

When you feel it starting, just slow down your breathing, and concentrate on each breath, making it as slow and deep as you can.  The feeling should soon pass.  If you find it difficult to do this, then try breathing into a brown paper bag, which will have the same effect.

Good luck.
