for the last several days I have woken up with feeling that I am not getting enough air into my lungs, and I therefore get anxious and try to take sudden (chest) breaths to get the proper sensation. after a few days of this, i went thru what I believe was my first ever panic attack and went to ER. they took chest xrays and performed EKG-- both indicating satisfactory results. the problem however has persisted. I am watching countless diaphragm breathing exercises too. I am also seeing a chiropractor and will see an Ear nose throat specialist too. I am also a stressful person who worries constantly and perhaps I have learned to breathe wrong.
