Chronic pain lasting years, in left arm, chest, and back.

Hi, my name is Julian. I have been having chronic pains in my chest, arm, and back for about 3 years. I have had multiple tests done such as CTA Chest, EKG, Stress Test w Echo. All of my results have come back negative and it is really taking a toll on my everyday life and the ability to perform normal activities. The arm pain is a feeling of fullness and tingling and comes whenever I am active. The chest and back pains come out of nowhere. I am running out of possible answers and am feeling hopeless. Just wondering if anyone else has experienced anything similar or has any recommendations.
