Any ideas what this might be? For the last week I’ve had constant pain at the top of my ribs - when I press it it feels like it’s bruised although there’s no marks on my skin. It’s extra painful if I cough or stretch my arms and when I’m changing position in bed. It almost feels like it’s broken but I can’t think of anything which could have caused it. I’m 61 and otherwise in good health. Should I be concerned or wait for it to go away? Has anyone had anything similar?
