Abdomen discomort. It can be appendix?

Since past 3 days I was feeling slight and sometimes sharp pain in centre abdomen ,right lower abdomen , and nausea after meal , vomiting ,dizziness ,the pain was just like kidney stone pain ,it was unbearable at night , I consulted different doctors , they recommended tests CBC ,Widal ,sgpt ,urine All reports were normal expect wbc and RBC ,they were high and in urine ketone ,albumin and bacteria were found , another doctor  further recommended hba1c and creatinine test as my father was diagnosed with diabetic ketoacidosis 3 months ago and he was admitted to the hospital with same symptoms as of mine But my sugar and creatinine was also normal , I changed doctor from allopathy to homeo and ayurveda, they gave me medicines for gas , weakness control ,mental strength and abdomen ,now since last night pain has decreased but still it arises after interval ,nausea feeling is there , unable to concentrate Now if it's not kidney disease or stomach infection then what it can be  appendix?
