Continuing tightness of chest

Anxiety makes your muscles tense up even if you dont realize it. Of course the nature of anxiety makes you think it's something worse like a heart condition but it probably isn't. It feels like you cant breathe deep enough but you're actually ok and getting the air you need but the complicated stress response makes it feel like this. And what do you mean your brain feels affected? In my experience I've severely hyperventilated (because I too thought I wasn't getting enough air) and it makes me feel dizzy, my head tingles and I cant think straight so if you're referring to something of that sort it's because you're hyperventilating and getting too much oxygen and not enough carbon dioxide. I cant explain all the science behind it but I ended up in the ER for it and they told me it's too much oxygen. The breathing technique I use is called square breathing where you breathe in for 4 seconds, hold for 4, out for 4, hold for 4 and repeat or another good one is in for 4, hold for 7, out for 8. Sorry for the lengthy response but I hope this helps!

Hello. Anxiety seems to have you in the chest, and maybe when you are attempting to take deep breaths to breathe, you are hyperventilating, causing your head to feel strange....please don't pass out.

If you haven't had a doctor's physical in awhile, you may want to arrange for one to rule out anything medical that could cause this......angina, congestive heart issues, etc.

I had anxiety pain nonstop in my chest for a very long time....finally resolved after therapy some meds and one of the nightmares changed. I had to be patient and deal with it the best I could until it resolved. We figured out what was fueling the anxiety (I'm PTSD), then it was figuring out how to "dismantle" it. My best wishes for your reduction in anxiety and pain.

I also see thing differently. I've been seeing things differently I mean but it's become more now too. Like it's not real.

It sound like anxiety again. If you could find a yoga exercise online that would help you control your breathing. You might even find a breathing exercise online to relax you. Or, an exercise to relax your total body one part at a time.
