Welcome to the forum! I have exp reflux problems for many yrs, and wanted you to know that I've had bumps occasionally on the back of my tongue, but not sure if they were from acid reflux.
The jumping up being awakened from sleep in panic may be a different story. This has happened to me in the past, my latest episode was just last night. I tell ya, it's really scary. I have been having a rough time with reflux and gas problems for approx 2 days now. So, this leads me to believe that this problem could possibly stem from GERD. I also recall exp this a couple of weeks ago when I was once again exp pronounced problems with reflux.
Of course, any new or persistent symptoms should be checked out by a licensed professional, but I just wanted you to know that you weren't alone.
Are you watching your food and drink intake????I know that I've been consuming more carbs and sugar lately than my body can tolerate. Sometimes, I go nuts with these things around or during cyclic cycles.
Good Luck! And, once again welcome!
