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?
Dear Madam, The tests that you are mentioning points towards the antiphospholipid antibody syn Chat Doctor.  You will need to see a rheumatologist for this.
