I've been experiencing some upper chest pain for a few days now. At first, I thought it was breast pain, but now it feels like the pain is more spread out around the area of my breast. I recently started wearing a wired bra about a week ago, and the pain began around the same time. Even though I've stopped wearing that bra, the pain hasn't gone away. What could be causing this, and should I be concerned?
