hi my 4 1/2 year old son has had diarreha for 2 1/2 weeks now sometimes it is really watery and other times it is just loose, also there are times it is really bight green and sometimes it is just dark, also he goes like 5 times a day and even has accidents where he thinks he is just going to has gas but some bowel comes out with it. When it first started he had no other symptom but the last week he has had fever cough and runny nose, which all stopped 2 days ago, we went to dr but she didnt do anything or say much, we do not have ins so i dont want to take him to er but I would like to get this figured out what should I do?
