hi all I am a 41 year old female, wife and mum of 3 , 

and I've recently had diarrhoea for 14 days with extreme pain which prompted a stool sample , my fit test score come back at 399 which my gp agreed was high so has referred my to gastroenterology as a routine referral - (there are no appointments at present so been told the will contact me by middle of April), my gp had asked me about any blood in feces which I said no to thinking bright blood but looking back I have had black or very dark stools in the past heres were the over thinking starts ....he also said my bloods were OK including fbc but I have regular b12 would that help with fbc , he also didn't ask me about any history but I've suffered with my bowel either loose or constipation for years now but yhe past 2 year have suffered with intense itching which during a telephone consultation during covid a different gp diagnosed as eczema but no creams have helped at all my question is could all this be linked and am I right to be worried and should I be talking to my gp again regarding these other symptoms thank you for taking the time to read this any advise no matter how harsh is really appreciated,  thank you xx
