welcome to healthcare magic.
from the description of the symptoms, you might be suffering from a urine infection you need to get your urine checked for urine infection as well as for blood sugar as you are urinating alot.
for the feeling of passing stool you could be having hyperacidity
which is causing gas accumulation and making you feel like that
if you have urine infection then you need antibiotics to clear it with adequate water intake,
if suffering from diabetes
you need to be reviewed by a physician for appropriate treatment.
for hyperacidity you need antiacids and you should try avoiding gasy foods, acidic foods, spicy foods, oily foods.
hope have been able to answer your query
wish you a quick recovery.
