<s>[INST] I have been experiencing a great amount of lower back pain these past few weeks. About 5 or 6 weeks ago I was hit in the back with someone s shoulder pad while playing football. I visited a chiropractor and he said there was nothing wrong and that everything looked great. Although the pain is still very intense and is keeping me from doing a great amount of daily activities. What do I do? What do I do? [/INST] Dear patient This seems high velocity back trauma and needs to be investigated with X-ray of lumbosacral spine anteroposterior and lateral views to rule out bony abnormalities.  If it shows fracture need to consult expert spine surgeon and get yourself examined.  If report is normal its back sprain and need to take rest for 3 days. Take tab diclofenac plus thiocolchicoside combination twice a day for pain relief. Apply nice gel locally at site of pain thrice a day.  You we be fine in a week. </s>
