Laura you're a classic!! Yes, I am a mum with sore bum sufferer!!!
I was actually fine all during pregnancy and for about 6 weeks after, and THEN it hit.....WHY OH WHY!! Anyway, I do the fibre thing, and Im pretty regular, but some days are just FAR worse than others. I actually bought anusol cream from woollies which has been great. I think the main thing is that I don't drink enough water. I really must drink more.
Im also going to have hot drinks like your Doc said Laura!!
Will come back with an update in a few days xo
