<s>[INST] Two days ago, I stood up and felt a severe pain in my upper back, about an inch to the left of my spine.  I am dizzy and feel weak.  The pain is worsened when I bend over or walk.  I am a fairly healthy 38 year old woman, although I do have a history of stroke and I smoke. [/INST] Hi, Welcome to HEALTHCARE MAGIC. MANAGEMENT OF acute back pain is rest in the position of ease ,analgesics(diclofenac),vitamin supplementation. LOOKING to your query it seems to be due to prolapsed disc It is confirmed by clinical examination and MRI scan.I think my answer will be helpful to you. </s>
