It hurts to sit.
It hurts to stand.
It hurts to walk.
It hurts to shit (whether hard or soft - even if very soft) A LOT (as in an 8 or so) and sometimes there is blood.
I really hope that, in this visit to my GP tomorrow, I do not wimp out and I push for tests and referrals. Sadly, thus far, I have been all British and not wanted anyone to 'poke around' back there to see what might be wrong.
