Hi,I ve had diarrhoea for 8 days now, including passing just mucus on several occasions, my appetite is slowly improving and I have had no fever to speak of.It began with a lot of abdominal discomfort and nausea, which has lessened as the days continued. For the last couple of days, I ve had a funny, fluttery feeling in my chest along with my heartbeat thudding in my back.I ve been to two doctors and they both have said its a long-lasting case of gastroenteritis, but I m still worried.
