MRI disclosed I have Lesions in my brainstem (pons to be specific). A year ago diagnosed with Pollymyealgia Rheumatica. Pain, trouble walking. Now my legs are so weak, they tremble when i try to stand straight up. Tremors. Weakness. Neurologist ordered blood work. My anti cardiolipin igm is 24 , the other cariolipins are <9. The Lupus anticoagulant came back negative, but the LA Screen is Positive , I do not know what any of this means. I am getting worse each day. Do not see doc till February 28. Had MRA of neck and head 3 days ago. No results yet. Any insight into these tests?
