### output:

Hello, I am a neurologist responding to outlet me explain to you that a given medical problem can be due to various causes. For example fever can be due to malaria, typhoid, urine infection Tuberculosis, cancer, AIDS etc. Back pain can similarly be due to various causes. It can be due to spondylosis, infection in the spine, cancer, and tumor and so on. The presence of two symptoms in you is really worrisome one weakness and the other the sensation that you feel. I understand that you had back surgery and later infection (note the exact infection in you is not clear to me whether it was tuberculosis or bone infection osteomyelitis etc.). What I feel that the presence of the two symptoms that you have listed need urgent neurological evaluation. I strongly advise you to undergo a detailed neurological evaluation by a neurologist and that will tell us whether you are an MRI scan of the spine or not. This will subsequently guide the neurologist regarding the need of Nerve conduction study. These examinations will guide us regarding the exact diagnosis, and you can be treated accordingly. Hope this clarifies
