Hello Snehal, Welcome to HealthcareMagic Forum.
Do you have Nausea
or vomiting? It need not necessarily be IBS, but get yourself examined by a Gastroenterologist to confirm it. Get a repeat Ultrasound
scan and a CT scan
done after consulting your Doctor. If everything comes to be normal, Kindly get yourself examined by a Urologist
so that he can examine you and suggest Urine routine or Blood Work up to rule out Urinary Tract Infection
or Kidney stones, since your history suggests dragging type of pain to your Thigh. Get a Ultrasound scan concentrating more on your Kidneys to rule out Kidney stones. Once confirmed the treatment has to be started.
Drink as much as 2 to 3 liters of water everyday. The treatment depends upon the size of the stone. No treatment is required if the stone is less than 4mm. Eat less salt and less protein diet. Eat Fresh fruits regularly.
Wish you Good Health, Take Care.
