I'm experiencing pain on the right side of my chest, specifically in the middle area, and it gets worse when I bend down, walk, or move forward. It's been happening since yesterday morning. Even sleeping is tough I feel it when I try to lie down, and it's really painful when I sneeze. I've been on medication for epigastric and antral ulcers for the past five days. Could this chest pain be related to that, or might it be something else? I'm really worried about what's going on.
