Pain under breast

I’m 29 weeks today. I’ve had an extreme pain under my right breast for most of my pregnancy but it keeps getting worse and is keeping me awake at night. Wearing a bra is absolute torture. I do not believe it is my rib or baby boy kicking me. It almost feels like really extreme carpet burn. If I touch it, it stings. Maybe breast tissue? The pain is in the area directly under my breast and also if I touch the bottom of my breast. Any ideas what it could be or how to cope? I asked my doctor and his response was basically that I was short so things were going to hurt, and to try sleeping on my left side. 🤷🏼‍♀️
