I'm experiencing some shortness of breath, especially when I'm trying to go to sleep at night. It wakes me up and I find myself needing to wait to catch my breath before I can settle down again. It's been going on for about 3 years now and sometimes it's accompanied by bloating, burping, and farting. I notice the shortness of breath can also happen with panic or loud noises around me. I've tried different medicines over time but they only seem to help temporarily. I'm really curious to know what could be causing this and what might actually help. What do you think I should do?
