Chest pain, clear hot diarrhea and nausea. What could be wrong?

Diarrhea/chest pain. May have gastroenteritis. The colon actually goes quite high at the top of the diaphragm so it can be confused with chest pain. Also consider reflux/ H pylori as H pylori can cause a diarrhea. Gallbladder disease and thyroid disease can also present with chest pain and diarrhea. Follow up with doctor urgent care.
