Its on the side of the torso, and its just under the armpit. Its not the obliques. Anyways mine on the left side seems a bit bigger than the right, but I'm right handed. I can take pictures if needed but it seems really large on my left side. Compared to the right side anyways. I want to say lats but I don't think it is... its a weird bulge on the side. It doesn't hurt or anything just seems out of place. It looks normal when I'm just standing but if my arms are up for any reason its bulged out.
