Just a hypothetic question here -- well slightly hypothetically. Say a patient came in complaining of some of these symptoms: tingling in my entire body, burning pain, weakness & fatigue in the muscles, stiffness, depression, headaches, major muscle cramps and spasms, a decreased ability to feel pain & heal from it, malaise, frustration, difficulty with memory, concentration & thinking. This patient also exhibits an abnormal babinski reflex (one sided), hyperreflexia, hyporeflexia. On parts of the body this patient has no feeling either. What would you first consider? What tests should be ran? What type of specialist should be sought.
