Welcome to the Healing Well GERD forum! It sounds as if you've come to the right place. The symptoms you've described are classic and very typical for uncontrolled GERD.
The breathing issue on inhaling is almost certainly your dysfunctional vocal chords that are closing when they shouldn't because of the reflux effects.
You really, really need to make an appointment with a GI doc and get in to see him/her. Once you're on a PPI/acid reducer, stay on it and give your upper GI tract time to heal.
You may find your LES (the valve that keeps acid in the stomach and not in the esophagus) is very weak, and the PPIs will be necessary long term. Get that appointment, and take along a list of symptoms and questions. It might be time for you to get some testing to see what's really going on.
Glad you've joined the forum! It's a great group, who will provide you with lots of support.
