5. Gallstones
The gallbladder is an organ that lies just below the liver. It stores bile and expels it during digestion. However, the gallbladder can become blocked by gallstones, which will prevent bile from being released and can cause a significant amount of pain.
The exact cause of gallstones is not known, but they are believed to be caused by either too much cholesterol or bilirubin in the bile, or if the gallbladder doesn’t drain properly. Whatever the cause, gallstones can cause severe, intense pain that can ebb and flow, and last for a long period of time.
They can pass on their own, but it’s best to see a doctor have the condition diagnosed and properly treated.
