I used to feel like couldn't catch my breath. I'd be taking deep breaths and yawning for days. The doc sent me for a breathing test and it was normal in that I was getting enough oxygen. I hated that feeling. I would get so sore and accumulate fluid in the tissues around my diaphragm too from forcing myself to breathe. Then it would pass and I wouldn't have it again for months. I found it happened when I was extra-tired. They checked my heart and that was fine too. Never got an explanation, but after it happened so many times and I didn't die, I just waited it out. Hasn't happened in a good while, I'm taking citalopram so maybe that's why.

As for trouble breathing: On the one hand I was noticing this or thought I was noticing something like this -- a year ago. For example when I bend to tie shoelaces. They sent me for a "stress test" treadmill. Results were fine. . ...... :)~

OTOH oxygen has a direct relation (and this is no surprise to some) to anxiety. I could give several sources but I won't bore you, suffice it to say doctors f2f have said it fairly directly.

So if one's oxygen gets just a tiny bit low at one moment, then one begins to be a bit uneasy. And to obsess.
/ I don't have a complete explaination, at all. Just a FYI.
/ Above std level of oxygen and ya' get weird somehow; but then too little.... Well 5% too little and you'll get busy trying to get more; even a part of 1% and a person'll feel uneasy and try to make adjustments.

The constricted throat I wonder might be (partly?) caused by uneasiness.

The body learns to correct this or that.

One should keep an eye on that doctor who didn't check back . :( My considered opinion.

Caleb, one of Moses' 12 spies. C and Joshua who fit the battle of Jerico were only one's who thot Canaan could be took . :)

I'm not concerned about my doctor not contacting me since doctors in my experience don't contact you unless something is wrong.

This is one of the main "symptoms" of anxiety. It is almost like you are hyperventilating even though you don't realize you are. When that feeling occurs you probably start to worry and wonder what it is because it is a scary feeling. But the more you worry and focus on it the worse it gets. If you can believe it is actually one of the easier symptoms to learn to control. When you feel like this, start breathing really slowly in and out and check that you are breathing with your stomach and not your chest. Try to do this every time until it will almost be second nature. It really does make a difference. As far as the chest x-ray, yes the saying is no news is good news but it certainly wouldn't hurt to call your doctors office and just say you wanted to see if your x-ray results came back. I just see that as being pro-active with your health. Good luck and take care.

Note last part of it . . . . The article talks about carbon dioxide, which in low levels is needed. Whodathunkit . :)

I found it with a Google search:

Thank you sunshine. I actually have an appointment tomorrow anyway:)

I have this same exact thing happen to me. Same as Sara59 said, I just had to wait it out. It comes and goes but the doctors say everything looks good so I do think it is just an anxiety symptom. I think it's actually pretty common, because it seems like a lot of people on this forum and others have gone through the same breathing thing.
