Yes, yes, OK, I'll see the doctor. I have to see him next week anyway, for blood test results, so I'll stick my squishy lump under his nose.
Incidentally, the lump itself doesn't hurt at all and, being where it is, I can move it around quite a bit. The elbow only hurts if the actual bone touches a hard surface (if the lump shifts a bit) or when I straighten my arm, when the bones touch together. The lump is unsightly but it's definitely acting as a cushion on the joint.
