LPRD?

I haven't been to a doctor yet but I've been having some symptoms that, after researching, sound exactly like LPRD. I don't know anyone with this condition. I was wondering if anyone here had it and if so, what does it feel like exactly? According to what I've read it sounds like asthma-like symptoms, a feeling of a lump in the throat, throat pain, and feeling like there's something stuck in the back of the throat, among other things. Are these symptoms chronic, or only after eating? What exactly does the "stuck in the back of the throat" feeling feel like (mine feels like a popcorn kernel, or sometimes a hair or something). Just curious. Any feedback I could get while I wait for my doctor's appointment would be appreciated. Thanks!
