Hello, I Am A 54 Year Old Male Experiencing Moderate

Hello, I am a 54 year old male experiencing moderate discomfort in my upper abdomen. This has gradually increased in frequency and level of discomfort/pain over the last 2 weeks. The pain is always located on the right side of my body,extending from under the breastbone downwards and to the right about 2-4 inches. It seems to be aggravated after eating. This discomfort seems to be growing and at some times could contain a burning feeling. WEB MD 's most likely culprit: Gallstones. What do you think? Can I wait this out?
