asazala,
I myself have never heard of anxiety being related to back pain.
maybe you have two things going on at once?
did the ER perform an x-ray of your spine when you went to the hospital?
certain back problems like arthritis of the spine can degenerate and cause bone spurs to grow, which is the body's way of healing the damage and maybe it's pushing into your lungs?
did they do a lung xray too? that's the first thing they should have ordered.
when a person can't breathe, of course they're pulse rate will increase and will cause a person to feel like they're having a panic attack.
I would suggest you follow up with anotehr dr if this one is not going to help you find out the cause of your not being able to breathe right.
sometimes lymph nodes inside the body can swell and cause pressure too and make a person feel they can't breathe.
there's so many things that can cause it. only a doctor can determine what it could be.
I hope you find the answer to your problem so that you don't have to worry that this will continue happening to you. that's enough to make a person have an anxiety attack even if they don't get them.
were you ever to a doctor when you're back pain started 3 yrs ago?
mine started out subtle like yours and has only got worst over the years. my dr told me to have an xray and that's when they found out I have degenerative joint disease in the spine and I have bone spurs also, It's another name for osteoarthritis.
PLUS I had dexa scan or bone density scan to test for osteoarthritis and I have that too.
both of these things can cause back pain.
I hope you get a diagnosis to your problem.
I wish you the best outcome.
sincerely,
Linda
