Need some advise please diagnosed with IBS many years ago and have been going back to GP due to pains and keep getting fobbed off until a couple of weeks ago insisted that I was looked at as I have pain all over stomach, really severe burning pains in area above pubic bone and sharp stabbing pains mainly in left hand side but also travelling across to right. Also have some back pain, about once a month I get serious diarrhoea with blood and that my poo is thin not fat as it used to be. At first gp did not seem bothered but then said she would run blood tests which have caused her alarm, I had tests on Monday last week and next day had several calls from receptionist asking me to go for more tests and they were still waiting for results, later that day the gp called to say I have low haemoglobin and whether I was still having periods, which I am not, I am 55, she then said you are bleeding internally could I get an iron test done and she would arrange an urgent scan which would be within 2 weeks, looking up anaemia it shows dizziness and headaches, something I have been complaining about for a year and for which I was sent for a brain scan, surely a year ago IBS, dizziness and headaches should have raised alarms bells, I asked whether it could be cancer, she said cancer is painless and that is why it is called the silent killer, that is not what people with cancer say and I am now petrified that as I have pain it is too later to treat should it be colon or bowel cancer, apart from pain I feel well and healthy have not lost weight and although appetite is down at the minute, think that it because I am sitting here wondering whether I will be alive to see my 15 ds leave school.
