Hi, Thanks for your question. After going through your question, I can understand your concern. The pain is most likely related to urinary system. Most likely a right ureteric calculus (stone in tube connecting kidney to urinary bladder). But other causes like pain of colitis should be considered. You should consult your doctor for detailed clinical examination. Depending upon it following investigations help in making appropriate diagnosis. - Complete Blood Count. - Urine examination. - Ultrasonography of abdomen and pelvis. - X-ray abdomen in standing position. Depending upon clinical examination and above test results further evaluation can be planned. Till that time use some pain killer with antispasmodic like diclofenac and Buscopan. Hope this helps you, if so do vote as helpful.
