Been having pain in my chest right under my collar bone in the middle. Only hurts when I turn or move a certain way.?

Strained ligament. If it only hurts when you move it might be a partially torn ligament that attaches the clavicle to the sternum. This can take months to heal. See your doctor and make sure that's all it is.
Musculoskeletal. It sounds like musculoskeletal pain. A lot of people don't realize that there are several joints associated with the ribs and breastbone. You could have inflammation in a joint as well. Check with your doctor but a course of a anti-inflammatory should help.
