I am always bloated, gluten free for years.

Hello everyone, I am very tired of being bloated. About 4 years ago I noticed I was bloated everyday. I struggle with pain in my lower left abdominal region as well. It comes and goes daily. It is a dull sort of throbbing pain. I am anxious over this pain as it began a year ago, and my bloating is constant. I never show my stomach wherever I go. Even when I eat less and stick to water and digestible foods, I remain bloated. It has really taken a toll on my mental health. My weight has been stagnant the entire time. Please share your experiences and any thoughts.
