Hello, Late last night while I was sleeping, I was awakened by a burning senstation in my throat and congestion in my chest making me want to cough. As I started coughing, it made me vomit. It was mostly brown and eventually, the burning sensation went away but I kept needing to cough or clear my throat afterwards. I also burped quite a bit after I vomited. All day today, I ve had to keep clearing my throat and/or cough. Could this be anice acid reflux episode??
