Hi, thanks for posting the concern in the Chat Doctor. A central back pain with yellowish discoloration of urine should be evaluated for any liver or gallbladder pathology. However, other causes of central back pain and/ or high colored urine should also be excluded. They are- Pancreatitis or any other pancreatic pathology, Peptic ulcer disease, non ulcer dyspepsia, renal pathology, small intestinal pathology etc. But, the primary thing we need to know to come to a diagnosis is whether you are at all interim or the urine is only high colored. A conjunctival examination by a local physician and more accurately a serum bilirubin test would help us understand whether you have jaundice. In that case, the causes of hyperbilirubinemia along with back pain will be evaluated. Otherwise, if it is only high colored urine, your HY Chat Doctor. Therefore, my understanding is, you should consult your local physician immediately for further clinical examination and evaluation. You may have to do the following tests-Complete blood count, urea, creatinine, sodium, potassium, LFT, amylase, lipaseUrine for Routine examination USG whole abdomen the time being, please maintain good oral HY
