In brief: LUQ anatomy

Anatomically, the left upper quadrant (luq) of abdomen includes: spleen, pancreatic tail, stomach, descending duodenum, splenic flexure of the colon, associated vessels.
Don't forget the diaphragm, heart, & lower chest are pretty close by. The abdominal musculature, ribs, & skin can all contribute as well to localizing luq pain. Get examined now please for clarity of diagnosis esp. if seeing blood
