I Have A Weird Lump Under My Ribcage That Causes Nausea

Okay so a few weeks back I was applying lotion to my torso and I felt this weird lump on the right side just under my ribcage. Kind of feels soild, moves a little like rubber and when I pushed on it I feel nausea. I do lay on this side a lot and I have no health conditions. I am a bit overweight and I have recently lost some weight about thirty pounds. I do also take adderall 20 xr for add. I made an appointment. just feeling scared and concerned. any suggestions as to what this may be or am I over thinking this. The lump isn t painful but like I said it causes nausea when touched or pressed on.
