Welcome to Healthcaremagic.
If you have gastro intestinal symptoms like loose stools or vomiting
then the chances of the pain you have to be due to appendicitis
can be possible.
Since you have history of burning micturation the chances of urinary bladder
infection being the cause are more.
You may have to be placed on antibiotics to get rid of the symptoms you have>do consume lots of water and Cranberry juice as this will reduce the load of the infection.
Wish you good health.
