Hi @nicolerose30, and welcome to Mayo Clinic Connect! You have found a good place for support as you go through the process of addressing your sternum/stomach discomfort possibly related to inconsistent digestive patterns.

@scottrl may just be on to something and others may have different ideas. I certainly am not a medical expert, rather continuing to learn as I go through the same process you are starting. I am glad you are going to work with a doctor who will walk with you through this process. A doctor who knows the science + you who knows your body = a productive partnership!

I relate to your stomach and back symptoms, along with constipation. It is frustrating. In my case, I learned I do have muscle coordination problems at the end of the digestive process that impacts everything up above. I look forward to learning what you find out.

Do you notice any connection to your symptoms and when you eat? Does being active and maybe walking after eating make a difference?
