<s>[INST] I ve had this pain in my back on the left side near the bottom of my rib cage. I started out, I thought , as a pulled muscle from work lifting heavy boxes while I was straddling some bins on 2 x 4 s up about 8 ft high while some one lifted them up to me. This was 5-6 days ago. after 3 days it seemed to get better however my friend rubbed it for me 2 nights ago very aggressively ( hurt like hell but I thought it would help ) and the next day it seemed a little better. However, today there is a defined lump that hurts alot when pressed but the lump is a bit farther away from the original pain site which was closer to the spine ( paraspinal muscles ). The lump is approx. 1 1/2 in diameter and raised just a little bit. Help, what might it be?
