Conversation: The conversation between human and AI assistant.
[|Human|] I got up from sleeping about 5 hours, walked to the kitchen, and my legs (both) started to feel weak and almost like spaghetti, not wanting to hold me up. I sat down in the closest chair for a while, went back to bed for 15 - 20 minutes and got back up. I seem to be ok now. I work at night and sit for hours watching patients in a sleep lab. My chair is not the best either. This has happened once before but not as bad. I thought I was going to fall. I have a BMI index of 30. I have injured my back over the years in car accident and horse accidents. What do you think? do I need to make an appointment to get x-rays?
[|AI|]  Dear sir/madam would like to know how long is this weakness episode lasted, do you have any tingling or numbness in your legs, i would examine power in lower limbs for objective evidence of weakness, and also check sensations in your lower limbs.examine locally for any bony tenderness in back. Then decide whether investigations are necessary. Based on your description it could be due to neuropathy, probably compressive in awkward posture.
