Hi, I'm Female 58, Long Term Migrant Sufferer. I Have

Hi, I'm female 58, long term migrant sufferer. I have pins and needles in my left arm, and outer thigh. I have had several drop attacks. My migraines have stopped since these symptoms started. My doctor did some Neuro and eye tests Left eye sluggish when flowing finger, right side normal. Reflexes were normal. I'm having a Brain CT scan soon. Doctor says it's very interesting and thinks it's a vascular issue at cerebellum/ base of skull...any ideas ?
