Scoliosis with a bump on ribcage between breasts

I was diagnosed 7 months ago with Scoliosis. I am 44 years old.

Have a gentle upper thoracic scoliosis convex to the right and a second gentle mid lumbar scoliosis convex to the left. With the thoracic results I am told my bones appear 'osteopenic' and so I am drinking as much yogurt as I can. Milk upsets my stomach.

I have a bump between my breasts on the rib cage which enlarges and then decreases. My dr. only said it is the last bone in my body to calcify. Sometimes this bump hurts especially when I bend over and put pressure on my chest.

Would like to know if this is another Scoliosis 'thing' to worry about?

Thank you.
