A family member has been suffering with very bad low back pain, diarrhea at times, low grade fevers sometimes, weakness, He just stopped warfarin (6 mo) because of a blood clot in leg. He is feeling sick and weak and no one can figure out what is wrong. He has had numerous blood tests and chest x rays and stomach ultrasound all coming back ok. Just the other day, we think he had a mini stroke, He had slurred speech..it went back little by little and now speech is fine. CT SCAN showed no blood. He goes for a brain MRI tomorrow to check further. We just don t know what this is....what do you think?
