Brief Answer: See Dr, chest X ray, blood tests, check dehydratio Detailed Answer: Hi and thanks for the query, I do understand how disturbing this could be. It is urgent to evaluate your clinical status why you experienced such severe diarrhea episodes, to know of you have signs of dehydration and manage them first. It is important to note any changes in your diet, whether you ate foods you were not used to. Such severe diarrhea episodes are very characteristic of food poisoning. Any recent travel history or eating out of the home could explain this. A viral infection could explain the flu like symptoms you experienced. However, a history of chest discomfort and cough would deserve to exclude an underlying chest problem. A medical history of lung disease or asthma has to checked for. It absent, I honestly think a chest infection of other underlying chronic infection would be of help. The stethoscope at times might not pick up certain lung pathologies. I strongly suggest you get a simple chest X ray done. This would guide so much a probable infection or orientate further investigations if need be. A complete blood count, C reactive protein and erythrocyte sedimentation rate done in the laboratory would also be very useful. White blood levels and specific differential counts would be useful in deciding if its an infection, and possible infectious agents. Chest pain for over a month could have various causes ranging from cardiac, digestive tract disorders. I suggest you get a complete clinical review. A chest X ray, C reactive protein measurement, erythrocyte sedimentation rate and a complete blood count shall be most useful. Appreciating and managing appropriately any residual diarrhea or dehydration status would be most useful. Thanks and kind regards as I wish you the best of health. Dr Bain
