<s>[INST] Hi, Two weeks ago, i woke up with low back pain, i didnt lift anything heavy or do anything to aggrivate it. Now i have pain on and off in the inside of my thighs. It started to get better with chiropractic care but now every time i try to walk somewhere, it gets bad again. Its almost impossible to stand straight up too, im always just a little slouched over now. What is wrong with me? By the way, heat and cold packs dont doa thing for me....neither does Advil. [/INST] Severe back pain with waling for few steps or standing for few minutes indicates there is problem at your lower back that is at lumbar spine and disc level. I strongly recommend you to go ahead with MRI of lumbar spine and based on the report do consult orthopedic doctor here the or tho will suggest you treatment either conservative physiotherapy management with medication or surgical opinion based on your MRI report. If you need, you can also take second opinion with one more orthopedic doctor or spinal surgeon.in case there is no much issue in MRI I also suggest consulting a good physiotherapist take a physiotherapy treatment which can help to relax your soft tissues as well as reduce the inflammation along with this do take complete back strengthening exercise program which will help you to improve strength and stamina of your lumbar spine. Take care. </s>
