This could be indigestion, constipation, gas, food poisoning, gastro esophagus reflux disease, ulcers in the stomach, urinary tract infection, kidney infection, They crohn s disease, appendicitis. This has to be thoroughly evaluated in order to find the cause. They usually present with abdominal pain that may be mild, moderate or severe, radiating, associated with vomiting, fever, inability to pass stools. Since you have mentioned that you have passed bloody stools, it may be also due to a chronic fissure, hemorrhoids. I would suggest you to get a complete blood test and stool routine and get an endoscopy done. You can use painkiller like ibuprofen twice a day after food for a week and consume a high fiber diet, use a local anesthetic cream like lignocaine 2% foe application after passing stools. Try this for 3-4 days, and then consult your doctor.
