<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have patient that presented severe backpain that was of sudden onset.making her unable to walk or even stand or sit down. she has previous history of the same problem and an xray was taken and showed ,there was dislocation of the disk and she was put on traction.what could be causing the pain? and what kind of management is best for her?  <response>: Hi, Most likely cause for acute onset backache is muscular spasm and not slipped disc. Second fact is disc herniation cannot be seen on X-ray, but we can assume it if there is reduction in disc height. MRI is the needed investigation to confirm disc herniation. If there is repeat episode of acute onset backache likely cause may be:1. Acute lumbar sprain2. Disc herniation with nerve compression. MRI of lumbosacral spine with screening of whole spine needs to be done. Please get it done from radiology center nearby you. Meanwhile, start tablet Attract P twice a day with tablet Regain one at bedtime. Strict bed rest on hard bed is required. Visit to orthopedic surgeon for detailed clinical Examination is recommended. Hope I have answered your query. Let me know if I can assist you further.
