Thanks for the query
What exactly do u mean by 'not finding stool material in the stool' Do u mean to say u were having loose stools?
Mucus in stool almost always means an infection, most probably of the intestines. You can take a combination drug like ciprofloxacin
for 7 days along with pantoprazole
40 mg for 15 days. If it doesnt subside then you will have to approach a gastroentetologist for a scopy. For the pain u can use an antispasmodic like hyoscine butylbromide
Have a healthy living.
