In the past I have felt a lump in my throat and thought it was probably nothing. Then a few nights ago (granted when I was really stressed out) I started caughing heavily when trying to talk. Then last night in the middle of the night I woke up with the sensation that I could not swallow. It went away quickly after I fully woke up. I have had problems with post nasal drip my whole life- but this seems much different. I have been noticing that I am more hoarse than normal as well. This symptom too comes and goes. My family says that I have been to several doctors (including an ALS specialist) and none have found anything so I need to stop worrying. But what else could be causing all of these symptoms?
