Stomach pain, diarrhea
suggest that you are having an abdominal infection. You may have an infection without the fever. You should always take a course of antibiotics. The other possibility is that you could be having a gastritis
which is a condition where there is excess f acid formation which also leads to regurgitation which causes pain and loose stool
. If you are vomiting a lot, try eating dry stuff like buscuits initially. You also have to maintain the body fluids. ORS may help in this regard. If vomitings still dont stop then drugs like domperidone
and metoclopromide might help.
Hope I am able to solve your concerns.
Have a nice day.
