My left hand and left leg become numb frequently, it happens many times since last week , after having food and while sitting in the sofa I feel this symptoms, 3 days before I was not able to speak words, I have back pain too and sometimes after urinate I become so weak I could not able to walk even, apart from this I don't have any headache or severe pain, my BP level is normal,  is this the symptoms of cervical spondilosis?
