Hi ! Appendicitis can be excluded more confidently by clinical examination than with any kind of investigations like X ray. Sometimes gall stones and kidney/ureteric stone may also give rise to such symptoms, and an ultrasound abdomen is considered to be a better modality in detecting stones, which you can go for after discussing with your treating physician. Also you can discuss with him for a liver function test with serum amylase and lipase. In the mean while, you should stop eating from outside like fast and fried food or alcoholic beverages, if you do. You can also go for some kind of prokinetic drug and proton pump inhibitor along with a probiotic on consultation with your doctor. I would suggest not to go frequently for enemas unless your treating doctor advises for it. Wishing you an early recovery.
