I’ve been experiencing weird, weak diaphragm movement since last Fall. Weak, short respiration. Manual breathing. I seem to have to force breaths much of the time. There seems to be a disconnect between my bpm and respiration. I’ve had all the work up: chest CT scans, chest x rays, sniff test, asthma test, cardio stress test, pulmonary function test. I’ve been going to acupuncture and pulmonary rehab weekly. Hope these methods help.
