Spleen pain?

I’m experiencing constant discomfort where my spleen is located. When I breathe in or move it feels like it’s rubbing against my ribs. I meet with my doctor in 5 days.

Can anyone offer some guidance?

I still don’t know what’s normal and what isn’t but this doesn’t feel right.

If it is something I need to get checked right away do I call my primary or the doctor at the cancer center?
