I have a doctor's appointment today at lunchtime and I haven't slept all night. I have had intermittent diarrhoea for several weeks. I'd be fine for a few days last week and then at the weekend it started again. I blocked myself up with Immodium which meant I was able to get to work on Mon/Tues but last night, I needed the loo and I passed this awful pinky/reddy brown mucus (nothing solid). This morning it's just pinky mucous in tiny amounts - no stool. I am absolutely freaking out as I know this is blood and as it's not bright red it can't be haemorrhoids and yes, I've "doctor googled" it and now I'm certain it's colon cancer. I don't know how I would cope. I am a single mum, 2 young girls and we rely on my job. I can't "not" work. I've had to ring in sick today as I'm totally exhausted and I've been given an appointment at lunchtime by the docs. OMG. Someone please help me.
