Lung hypertension: At your age you should not have any pulmonary hypertension and the pressures you reported should be looked into. See a pulmonologist that works with pulmonary hypertension. Be sure your bring a copy of theECHO on a disc with you and the report as well.

Get seen: No physician knows everything. You need a follow-up with a specialist.
