Hi. I have had yellow watery diarrhea along with some sharp abdominal pains and deep cough in my chest. The cough has be persistent for more than  a week. The diarrhea started a week ago. Tonight I got the chills and had to soak in a hot tub to warm up. I feel as if I have a fever as well -  this is very unusual for me. I typically get head colds once or twice a year but this is different and lingering.
It could be atypical pneumonia. Atypical pneumonia could present also with diarrhea. You need X-ray, sputum culture and sensitivity to confirm diagnosis. Once confirmed you will be started on antibiotic by your physician. Make sure you take the full course of antibiotic that is prescribed by your physician. Never take over the counter antibiotics. Taking over the counter antibiotics is one main reason for developing antibiotic resistance.
