Hi @manojuan619, While you wait for members with experience to respond I thought I would share these related articles with you that I think support that xiphoid pain can be GERD related.

"Because of the location of the xiphoid process, oftentimes, xyphodynia can send practitioners pursuing alternate diagnoses such as GERD, helicobacter pylori-related ulcers, or other potential causes that are abdominal in nature."
