<s>[INST] yesterday, I started to notice that the muscles in my legs were slow to work. I also noticed numbness in my finger tips. I have no pain. I don t think I could walk up stairs because I would have to concentrate on my muscles in my lags to coordinate. It seems like it is more the outside muscles along my legs and it is those muscles that take time to do what they are suppose to do to keep my knees from buckling. I would describe it as rubber knees... [/INST] Hi, I have read the details and in opinion you probably have either a slipped disc or spinal canal stenosis(narrowing of spinal canal), which is causing pressure on the nerves, resulting in weakness in muscles and numbness in the tips. I would recommend MRI of Limbo -Sacral Spine to confirm the diagnosis. The treatment would depend on the finding. If it is Lumbar Canal Stenosis then you may benefit from surgery. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
