You could be suffering from an inflammatory bowel condition such as Celiac Disease/Ulcerative Colitis/Irritable Bowel Syndrome/ Crohn’s disease. All these result in tender abdomen, loose stool or loose stools alternating with constipation, abdominal distention, cramps etc. Parasites in the gut like threadworm, tape worm, giardiasis etc can behave this way. Hence a stool test is a must. Problems of gall bladder and liver or that of pancreas too cannot be ignored. Possibility of H pylori infection should be looked into by carbon urea breath test.
I would strongly recommend you to see a gastroenterologist (a specialist who looks after the diseases of our digestive system). Maybe your physician can recommend someone.
A number of times a gastroenterologist is able to diagnose these conditions by clinical examination and detailed medical history. At other times a few tests are conducted. Blood tests to rule out anemia, stool test to look for white blood cells, sigmoidoscopy, colonoscopy etc are used to diagnose ulcerative colitis. Braium meal and follow through, endoscopy etc are done to rule out GERD, Crohn’s disease etc. Irritable bowel syndrome is diagnosed by elimination of other causes. Gluten is a complex protein present in four main grains---wheat, rye, barley and oats. If you have gluten intolerance, then you probably have celiac disease or Non Celiac gluten sensitivity. There are blood tests called celiac test to detect gluten intolerance.
Crohn’s disease is a difficult entity to diagnose. Along with gut symptoms skin disorders and arthritis too are commonly seen with Crohn’s. An upper GI series using barium dye is done to see the condition of small intestines. The degree of involvement of the large and small intestine may vary from person to person. A biopsy is the most confirmatory. An elevated ESR, low protein, minerals and iron in blood are the other findings in Crohn’s which may or may not be present. A recent advancement in Crohn’s diagnosis is video capsule endoscopy.
Please discuss this with your parents and consult your PCP for primary examination followed by proper referral. Hope this helps. Take care!
