<s>[INST] is this really a doctor?im dealing with bad upper back pain-5yrs now, still trying to find out whats causing it. i had a car accident. upper back pain feels like burning stabbing continuous pain. right on the spine is tenderness, used to be extremely painful when pressed lightly. went through 6 weeks of chiropractic treatment recently (felt extremely painful afterwards everytime!!) and the last one left me even worse. now my neck has pain and feels weak and i have sciatica, i feels like both but maybe just left (unilateral?) a lot of pain in buttocks, usually stops at the end of the thighs (back) tail bone hurts too..weakness in legs, a little numbness, most of the numbness is in my lower back.. what do you think? [/INST] Dear Patient, your back pain needs proper evaluation and diagnosis, and an MRI of the region is the primary requisite beyond good examination, if there is compression on the nerves in the back, you may need surgery, but you should not just depend on chiropractic treatment, moreover beyond disc diseases other conditions can also cause such symptoms, and you will need and MRI to come to an end in this evaluation of the cause. So consult your doctor and get examined and investigated. Any further query is welcome. Thanks </s>
