It feels like it’s located near/at the former/renewed joint between my xiphoid process and the main part of my sternum (down at the bottom of my breast bone for you new to busting ribs). It’s roughly 32mm x 6mm, oriented horizontally. There’s no pain when I press on it but it doesn’t slide around, suggesting it is attached to the bone, like the other lumps on my ribs.
My medical history includes breaking ribs on multiple occasions, most recently a year ago when I totaled my car in a headon. Of course I wasn’t wearing a belt (mea maxima culpa), which is a favorite way to break ones xiphoid process. The radiologist appears to have been more interested in my five broken ribs than anything they were attached to.
I will mention it to my PCP when my insurance starts (soonly) and will think healthy thoughts until then.
