A few years ago, when I was just finishing up breastfeeding, and had boobs like cantaloupes (and incredibly sore), I went to the GP about a lumpy bit.
He dealt with the concern (felt like a blocked something, which would go down as my milk dried up), but then went on to demonstrate fully how I would "check myself" in the future when the swelling had gone down. It hurt, and afterwards I realised it had been entirely unnecessary - it was not why I went. So - a an extra-dutiful GP or a bit weird and pervy? The memory still makes me wince a bit.
