Breathing...

Ok so when I lay down I can only lay on my left side. If I lay on my right I get terrible acid reflux. But last night when I laid down I felt like I couldn't breath. Like someone is sitting on my chest and I feel like I have a bubble like I need to burp but I can't. I just laid down cuz I got dizzy and it's happening again. I have a stuff nose cuz my allergies are kicking up. I sat in the bathroom with the shower on as hot as it could go to steam it up and it didn't help.

I have a doc apt tuesday and I'll ask then but I'm slightly worried. Should I be? What should I do. I don't want to go to the hospital cuz I have no one to watch my 3yr old.
