I am a 42 year old female. Yesterday, I started having a burning feeling in  my lungs, as if someone set them on fire. I went to work today  but had to return home this morning. I feel tired beyond normal and i threw up. My chest feels real heavier but I do not feel like I have a fever.
Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having HERD (gastroesophageal reflux disease) mostly. But better to get done ECG to rule out cardiac cause. If ECG is normal then it is mostly due to HERD. HERD is due to laxity of gastroesophageal sphincter. Because of this, the acid of the stomach tends to come up in the esophagus and cause the symptoms of burning chest pain and vomiting. Try to follow these steps for better symptomatic relief. 1. Avoid stress and tension. 2.  Avoid hot and spicy food. 3. Avoid large meals, instead take frequent small meals. 4. Start proton pump inhibitors. 5. Go for walk after meals. 6. Keep 2-3 pillows under head in the bed to prevent reflux. Don't worry, you will be alright.
