Hi.
Thanks for your query.
Noted the history pain in stomach for 3 weeks like a knife in stomach -changed diet, fine with rice, bread and cake, tried baba milk,
probiotic natural smooty and caused pain - kale also caused pain, wants to know how to get rid of.
Since you have pain for the last 3 weeks, it may be related to the intestinal infection and/or intolerance to certain foods but it is difficult to explain how would it start all of a sudden..
Hence I would advise you the following:
Clinical evaluation and examination.
Tests of stool and blood.
Ultrasound and X-ray of the abdomen in standing position.
This will get you the correct diagnosis and a proper plan of management.
Identify the foods and beverages that cause the problem ans stool these strictly.
