I’m so tired and I just need guidance.

I have a confirmed hiatal hernia and I’ve been on esomeprazole for 7+ years. Suddenly out of the blue, I’m now dealing with coughing attacks, a burning sensation in my chest and throat that won’t go away. This started about 5 days ago and I haven’t slept well ever since. I’ve gotten just a few hours of sleep each night cause I keep getting these coughing attacks. I went to the doctor and was prescribed Sucralfate and Flonase to help manage the symptoms as best as the doctor could guess. I’m still struggling after both of those though. I just want to cry. Why won’t anything help here? Is this what LPR is? Should I be investigating other things as well?
