<s>[INST] Hi My mom 55-56 years old is having severe buring sensation and immense pain in in her stomach area. she vomits out whatever she eats and no medicines seems to be working on her. She hasnt been able to throw out waste since like 5 days now.what is wrong with her and what tests should i do and how much will it cost me..Please advice ASAP.Thank you for your advice. [/INST] HI. The symptoms of persistent vomiting, acidity and burning sensation in the stomach along with constipation can be due to an intestinal construction. Considering the age of your Mother I would like to advise upper GI endoscopy, CT scan of the abdomen, colonoscopy and other blood, urine and stool tests (after enema) to see the cause of these. You may please consult the Surgical Gastroenterologist. We have to rule out Colorectal Cancer, Gastric ulcer or cancer, Tuberculosis of the abdomen.  This may give a guideline for the further investigations and management. </s>
