Hi Doc, i have a question regarding my condition right now. It started 2 weeks ago when i felt dizzy, i almost fell down..i keep on burping and feeling weak, and feeling light headed, there is like a burning sensation inside and sometimes difficulty in breathing, its like there is something stuck inside my chest. I was rush in ER twice but all the test such as cbc, ecg, blood sugar test were all negative. They said that it might be related to gastro. I went to another family doctor and she said it is an anxiety problem and has been given medication related to it. I have this problem intermittently, sometimes im ok and sometimes im not. Hope you can give some idea on this and who to approach.. Thanks doc.
