Thanks so much everyone for all the tips and advice, I could never have got all that advice from the Doctors.
Littlemum, although I have a healthy diet, to be honest I was snacking on chocolate, crisps and diet coke inbetween, not drinking nearly enough water and not enough exercise. Have started having hot baths, will try the essential oils too. I do remember having lavender baths after give birth which were very soothing.
Bellabear, thanks, someone else has suggested the linseed too.
Samvet, I don't know for sure it's a fissure as I couldn't get an appointment with my Dr on the day I rang so had a phone call instead. She said the symptoms sounded like a fissure, to try the GNT for 2 weeks and if no better to see her. Will ask her about the hydrocortisone cream if I need to, thanks for that.
Lynzilove, yes I'm at the stage of being terrified to go to the toilet. Reassuring though to hear positive stories.
Am off to Holland and Barratt tomorrow for my supplies ...
