<s>[INST] I have had lower back pain (I thought it was due to my cats not giving me much room on my side of the bed) this started 4 days ago, but has really escalated today. I now realize it isn t my back but inside and it feels like it s spreading from very low back to my mid back. I have trouble sitting, laying down or standing for any length of time today. I was barely able to drive a short distance today because I was unable to turn properly. I want to add that I am extremely active, I am definitely not over-weight, and like I mentioned this just kicked in a few days ago, today being the worst. Any advice would be greatly appreciated. I plan to make a doctor appointment, but with the holidays....doc is not available. Thank you [/INST] Dear patient You are having back spasm that is due to abnormal sleep position. I would advise X-ray of lumbosacral spine anteroposterior and lateral views to rule out bony abnormalities.  If its normal or showing loss of lumbar lordosis diagnosis is confirmed.  Start tab diclofenac plus thiocolchicoside combination twice a day for 5 days. Take tab attract one at bedtime. Avoid forward bending and weight lifting. Do hot water fomentation for 5 days. All this measures will definitely relieve you of back pain.  All the best. </s>
