Hey I have constant burping and a knot in my throat , I had acute bronchitis last year and haven't been the same since, I have smoked cigs for 9 years and joints for 7 but I stopped smoking joints 4 months ago, still smoke cigs, sometimes I get discomfort after smoking I also salivate a lot , since I had acute bronchitis I get anxiety a lot, I wanna know is this a cricopharyngeal spasm or something else ?
