I'm dealing with heartburn, chest pain, nausea, and shortness of breath, and I've been like this for the last six months. Ive had a 2D echo, ECG, vitamin D check, endoscopy, and blood tests, but everything seems to be normal. What could be causing these symptoms if all my tests are showing up fine? I'm really concerned and would love to understand what's going on.

Probable diagnosis is Gerd, patient is advised pan d ,orally.once daily for 14 days before food..Avoid spicy foods.
