Abdominal Pain and Inconsistent Bowel Movements

Patient: Since October I have fluctuating patterns of inconsistent bowel movements (usually 1-3 times a day it varies and the color and consistency does also between bowel movements) and abdominal pain, what could this be and how can it be treated? As well as some upper chest pain that I am unsure if its related or not.

Symptoms: Abdominal pains, inconsistent bowl movements, upper chest pain
