<s>[INST] I recently tried doing something very stupid on a set of stairs, I went through the bars and hit my back on the lip and my back popped. the middle of my back where I came down on hurts something fierce, ive been having cramps as well in my abdomen region along with the ach in my back... can you explain what I might have done to my back ? [/INST] Dear patient you may be having blunt trauma to your back with muscle spasm. I would like to advise xray of the dorsolumbar spine anteroposterior and lateral views to rule out bony abnormalities. Please get it done from radiology centre nearby you. Meanwhile start tab myoril 4 mg twice a day with tab ultracet twice a day for pain relief. Ice fomentation locally helps in reducing inflammation. if not relieved in 5 days please consult orthopaedic surgeon nearby your area with report. </s>
