(Edit) Thanks for the response doc, you were spot on with what my doctor said and did. Chest X-ray came back normal (No mass or visible sign of a break). So he was thinking it might be a hernia. He had me come in for a re-evaluation and during the poking and prodding he pressed on my stomach which caused a good amount of pain. He s thinking I may have had a very small hairline fracture of the xiphoid process which isn t showing on the X-ray and at the same time gastritis. The swelling of the xiphoid process was noticeably smaller on the last exam and couldn t feel anything that could be a hernia. He wants me get some blood work and a gastritis breath test then go from there. The pain has been decreasing this week which is week 3 and after taking some antacids is almost gone now. Wants me back in 10 days for a follow up. On another note after loosing the weight I am no longer pre-diabetic(End Edit)

A few weeks ago I felt a pop at the very bottom of my sternum while rough housing with the dog. I feel a lump there, but I m not sure if it is my xiphoid process and just never noticed it before. I did loose 15lbs on a diet though since the doctor said I was borderline diabetic back in may so maybe I can feel it now. 2 weeks later it is hurting and there is pain in my lower ribs and sometimes random spots on my chest and what feels like stomach and esophagus as well. I do have a long history of indigestion as well. Also I cough white phlegm first thing in the morning. My lungs feel fine, no problems breathing, but whe I get the pain in the random chest spots it feels like inflamed between the lung and ribs. It all feels better when standing, I go in for a physical on Tuesday and just wanted to know if I should try to go in to see the doc sooner?
