Curious as to whether or not you have had COVID? COVID made my reflux and IBS worse. Colitis and IBS are differerent, but, have some of the same symptoms. I am on Protonix 20 mg a day and 1 Pepcid AC at night which helps tremendous with GERDS. I have lost weight and still working on it which greatly helps GERDS, nothing to eat after 6:30 p.m. except an apple or skinnypop popcorn. Elevate the head of your bed, do not wear tight clothing around your waist, try and steer clear of caffiene, onions & acidic fruits such as pineapple. Try and not eat heavy meals. Drink lots of water. I have chest pain with GERDS when it is flared up and especially so after COVID. Since you are waking up with this, I'm wondering if you are having backup reflux, which can cause more pain. I take over the counter Gaviscon, 2 tablets before a meal if the GERDS is rough and I also take the Prince of Peace, Ginger chews. Also, have you hand an endoscopy to scope your esophagus to see if you have a hiatal hernia or something going on inside of your esophagus? This is a very painless and quick procedure. GERDS can cause chest aches and pains. Sometimes you have to switch toanother reflux medicine to get relief. Ask your doctor about this please. Keep me posted. I care. Praying for you.
