Hello, I Have Been Having Symptoms Of GERD And Am

Hello, I have been having symptoms of GERD and am on PPIs. In the evening I get a painful feeling that something is caught in my chest. It is better when I get up in the morning. Tonight it's so bad that I feel like I may choke. What can I do to get relief? It's so uncomfortable and painful. Feels like a rock stuck in my chest. thanks
