I get short of breathe walking around the block, but I'm out of shape.

I have had shortness of breath and dizziness. Not sure if it is fibro, asthma, or heart. Just know that it happens out of the clear blue. I could have worked an eight out shift, come home, and start getting ready for bed and all of a sudden I feel dizzy and short of breath.

sometimes I get light headed and sometimes I get the blackouts when I stand up, I have to hold onto something

Yes! It is not constant but occasional. It nearly stops me in my tracks.light headedness is an extremely common symptom for me.

I get out of breath very easy .I've given up smoking because I suffer from emphysema.i worked in a chemical factory making car paint and I think this has a lot to do with it.i also get dizzy.x
