<s>[INST] I have had no cartilage between the vertebrae in my lower back for years. I fell on Sunday and have had excruciation pain since. The doctor prescribed a painkiller, which seems to ease the pain at times, but it takes a long time for it to kick in. any suggestions. [/INST] Hello, As first line management, you can take analgesics like Paracetamol or Aceclofenac for pain relief. If symptoms persist better to consult an orthopaedician and plan for an MRI scan. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Shinas Hussain, General & Family Physician </s>
