<s>[INST] Hello doctor, I am a 46-year-old female. I have burning discomfort in my legs, buttocks, arms, hands, and lower back for six days. There is no weakness, no tingling, no numbness, no confusion, and no stroke symptoms. My friend told me that I might have multiple sclerosis. What could it be? [/INST] Hello. I would like to know some more details about your symptoms, 1. Did you have burning sensations over the whole body below the neck at one time? Or had uneven patchy distribution? Or the location of burning sensation was varying with time like, sometimes at legs, sometimes at arm and sometimes back? 2. Do you have any neck pain or lower back pain? 3. Did this burning sensation start suddenly? Or it gradually progressed and is it persistent? 4. Is there any particular position of body or activity in which this burning increases, during walking, neck flexion, and forward bending? Or any specific situation like stress or anxious state? 5. Have you any urinary symptoms like urgency, frequent urination or urine incontinence? 6. Do you have a history of a burning sensation or other neurological problem? 7. If burning is episodic, how long does it last? And is it also associated with palpitations and breathlessness? 8. How is your sleep? And how is your mood these days? 9. Have you any other medical problem too, like diabetes mellitus or a heart problem? </s>
