I cough stuff up for days.
This isn't exactly common but is sometimes seen with reflux. In my house we refer to it as "throw up burps." They can be very painful and can also cause reflexive coughing. Your lungs can also constrict in an attempt to protect themselves from the acid. Once the acid is there and has caused the damage it can take a while for the esophagus and throat tissue to heal. Because your symptoms are so severe - you should see a doctor to develop a treatment plan. You may also want to consider some preventive things such as sleeping in a more upright position, avoiding foods that trigger your symptoms or avoiding eating later at night.
Do you know of any instant relief when this wakes you up at night so you can stop the burning in your throat? I heard honey will help. I know I tried milk and tums and eating something and nothing seems to help the burn.
We do Tums. They seem to be the magic cure in our house for many things (hiccups and the throat burn). I've heard people recommend a warm salt water gargle. The biggest issue though is the burn comes from the acid literally burning the skin as it comes up. So, much like if you burned your arm - it's going to hurt for a while no matter what you do about it.
The best solution is to try and figure out what's causing it and try to keep it from happening again. Sometimes avoiding food for a certain period before bedtime helps. Sleeping more upright. Keeping a food log to see if there are certain foods that seem to trigger it. (greasy or heavy foods are a culprit in my house).
