I have read your question,
You are suffering from stomach infection
, you didnot mention the type of stool you are passing since it matters in this case ,Generally stool with mucus means amoebiasis
and if the stool is loose , it is amoebic diarrhea (pain around the umbilicus(=navel) .The chest pain
can also be due to acidity problem that arises due to irregular diet.
So I Recommend you to eat fenugreek (methi) Seed powder after each meal this will cure your frequent passage of stool , take antacid if you feel burning sensation and donot eat spicy meals , follow this procedure atleast for two days.
If you dont feel any difference , take anti-amoebic tabs ,deworming tabs and anti-biotic tabs for a week.
For further medical advice
I suggest you to consult gastroenterologist
Wishing you a good health,
