Normal PFTs: You don't tell us what your fvc is, nor your weight. Your fev1 is high normal, residual volume and diffusion capacity are normal as well. These data essentially rule out a severe problem. The low erv can be due to: incomplete exhalation and obesity being the most common reasons. The normal rv makes air trapping unlikely. Your symptoms are unlikely to be due to your lungs. Talk to your physician.

Incomplete report: Another set of measurements which will help define whether there is air trapping is the RV/TLC ratio which should be listed on the report. It can be elevated in obstructive disease. I hope that this helps.
