I’m experiencing an intermittent dull pain in the center of my chest that feels like it’s coming from my breast bone
as opposed to deeper within my chest
. It worsens when I lie on either my left or right side. Pressing on my sternum and ribs worsens the pain only very mildly, nowhere near the extent that I’d expect from cartilage damage, bruised ribs, or pleurisy, the latter two of which I’m familiar with from having had in the past.
