Trelegy inhaler side effects - need advice

I used the Trelegy inhaler a couple of days ago. I didn’t like how it made me feel, all jittery and teary. When I take the pulmonary function tests and they use an inhaler, they don’t improve my breathing on that part of the test. I can tell a difference on the days I don’t take fluid pills. I appreciate all of your comments. They are very helpful. Thanks.
