Hi. I'm new here. My daughter is being worked up for MS. She's had 3 MRIs with contrast in brain and spine. No lesions in the brain and only one on the spine at C2-3. Her symptoms are numbness and tingling in the right arm, hand and upper torso on the right side. However, very recently she has been experiencing severe pain in the right arm after eating dinner. Not sure why but another site referred to CCSVI as a possibility. Chronic Cerebrospinal Venous Insufficiency (CCSVI) is a term used to describe a potential reduction in blood flow in the major veins that drain blood from the brain and spinal cord over a prolonged period. The condition was first described as being a possible contributor to MS by Italian physician, Dr Zamboni in 2009.
