Recently twinned Head & Neck MRAs (to rule out stroke pursuant to repeat Hemiplegic Migraines) revealed the incidental finding of severe left subclavian stenosis. I will need to head to a cardiologist for further evaluation, since I have advanced neurological symptoms that may or may not be partially due to “Subclavian Steal”. I live in Chicago. We have no ME/CFS experts here. I’ve attended the Stanford ME/CFS Clinic and am a patient of Dr. Bonilla. No one has recommended any formal testing related to cardiology or to demonstrate my exertional and post-exertional symptoms. At the urging of my doctor and loved ones, I will soon begin the process of applying for SSDI. To bolster that and to help me medically, what cardiology-related testing is often (or sometimes) recommended for patients with severe SEID/ME?
