I feel like i have a burp in my upper chest that needs to come out but i cant burp or throw up to make it go away. its felt like this for 24 hours now?

It could be Acid ref: You need to tell us your age and other medical history. I would ask you to try taking an antacid like pepcid or Prilosec, both available over the counter. If not a liquid antacid like Maalox may be even better. If this symptom doe snot go away in 2-3 days, then you should go see a doctor. Sometimes this can be a symptom of Heart problems...especially if you are over 40 years or older.
