This sounds alot like Anxiety...have they ruled out Anxiety Attacks? I know when I have an anxiety attack I feel chest pains (like someone is sitting on my chest), I get chills, light headed etc... I too have had stress tests done, to no avail, but turned out I was experiencing anxiety attacks. After my third visit to the ER, they finally diagnosed me as having major anxiety attacks (which can often feel like an MI (myocardial Infarction ...heart attack). Try seeing someone who specializes in Anxiety disorders and see if that isn't the cause behind all of this. If it's not that, then I haven't a clue as to what it could be. But stay healthy and stay safe and KEEP ON trying to get this figured out!! Good luck! Keep us posted!!

You might want to ask about a stress test for her. They are pretty conculsive and would tell you physican a lot more. Has your wife ever had one done? Have you talk at all to her doctor about this. I think you should.

Hope this helps,

her symptoms sound a lot like anxiety. their maybe nothing wrong with her physically, but mentally thier maybe an issue. the mind is a powerful thing. i have had many panic attacks over things which have not ended up being physical and subjected me to think it may be mentally. you must stand by your wife , talk to her maybe somthing is bothering her ect. i know in my case what made me get worse is not talking about my problems which escalated my fears and panic attacks.

im proberly not the best one for answers as im still going through my own issues but i hope your wife gets well soon because no one deserves to go through anxiety

But, with any systoms that include chest pain can not go overlooked at anytime. Nothing to fool around with. Yes, you may have chest pain with anxiety or even acid reflux condition. But, IMHO chest pain is a red light for me and always has been. Did they do a "thallium" stress test on her. It's just that all those symtoms combined worry me somewhat.
Sure seems like she has had all angles covered. I guess her blood work came out alright yes? I am really at a standstill here. I guess next step would be to seek a different area of medicaine to check her out. Stress can give alot of those symtoms.
