What could cause dull pain in center of chest? saw cardiologist had stress test, cardiac ct, and echo... all ok. also saw pulmonologist... lungs ok.

GERD: The most likely diagnosis in a 31 year old man is gastroesophageal reflux disease, peptic ulcer disease, gastritis, esophagitis, or non-ulcer dyspepsia. It is clearly not your heart or lungs. A less likely diagnosis is costochondritis, myofascial syndrome, or fibromyalgia. I'm assuming you've had no trauma to your sternum(?)

Gastro related ???: Sounds like you have had a good work up already. Gastrointestinal issues such as reflux disease, esophageal spasm, gallbladder and others, as well as musculoskeletal problems such as costochondritis can cause your symptoms. It all depends on the nature of the pain and what brings it on or makes it better. Cont to follow up with you Doc until you get an answer.

Chest pain: First of all, thank you for first seeing the cardiologist and pulmonologist. Other systems that affect that central chest region include the gastrointestinal and musculoskeletal systems. Consider a visit to a Gastroenterologist to see if the problem is reflux or other GI issue. Next look at how you sit, if you are hunched over a computer all day, are you under a lot of stress? Still lots to check
