[|Human|] 4 yrs. ago, When I put my weight on left leg, down I went. No warning, never happened before. I have not been able to stand or walk since, without using walker. Have been to Drs.,had test, still no answer. Legs are getting weaker, very shakey. Afraid I will be confined to wheelchair. Do you have any idea what could cause this? Thank you very much. Liz Riley
[|AI|]  Hello, I have studied your case and I think that it can be due to nerve compression in the neck or brain that you are having this problem. I would recommend you to follow these steps.1. Get MRI of the spine and brain.2. Also check your B 12 level.3. You should take opinion from a neurologist. He may advise you if you will need any nerve decompression procedure.  I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks
