<s>[INST] I had lyme disease in June. Ever since then I ve had pain and burning under my right rib cage and pain around my back. My doctor thought it was gallbladder problems. I had a ct scan and it was negative. I have an appointment with a gastro doctor on the 16th. The pain is getting worse and is constant. Any ideas on what it could be? Nothing makes it worse or better [/INST] Hellos per your description of the clinical symptoms it seems that the followings can be probable reason for your discomfort- 1. As already described by your physician the most probable cause could be a pathology of the Gall bladder (cholecystitis or cholelithiasis).2 The second most probable cause could be a pathology of the liver or the hepato-biliary system. It should accompany certain other symptoms like nausea, vomiting, dyspepsia, flatulence etc.3. Any kind of muscle spasm or sprain.4. A Costco Chat Doctor. A USG of the whole abdomen and blood tests (liver function test) may give you a diagnosis. Please visit your Gastroenterologist for further evaluation and man agent. Thank you. </s>
