Dd3 has been constipated for a while and has been complaining of pain when passing poo. She's had small amounts of red blood when wiping after some of these poos. I've assumed it's something benign like anal fissures? From getting so constipated. But the poo is very pale - straw colored. Should I take to gp? She's otherwise well except for complaining about the odd tummy pain (before she poos) and also I think she's got slightly yellow feet - but I took her to the gp about that and they practically laughed at me re that. Should I go to gp? Any ideas what it could be or how I can help her other than lots of water and prunes?
