Dear Ms. Dunayew:
Sorry to hear about your multiple problems. It is difficult to tell you exactly what is the cause of your problems with the information at hand. Usually, when we see symmetric or at least bilateral problems we begin to think of systemic causes for an illness. The many problems you have might fall into this area. If the problem were something like B12 deficiency, alcohol, lupus, diabetes, hereditary (genetic), toxins, etc the laboratory data, family history, and physical exam would have begun to sort out the problem. Maybe more rare things should be begun such as amyloidosis or other autoimmune disorders besides lupus. To make matter worse for you is the preveious surgeries. These can cause many problems you describe and need to be factored into the equation of symptoms. Likely a detailed evaluation of before surgeries and after, the progression of symptoms, the current neurological exam with comparison to the other previous exams, lab results, MRIs will all have to be further evaluated.
Sorry I am not much help.
