My daughter is having pin prick sensation in her hands, feet, and has had convulsive like tremor..Says if she sleeps on her side it isn t so bad.. She is a size 4 or 6, tiny, no history of diabetes..She surfs almost dailey, eats all the right foods, never fast food (never ever). Could this be from Whiplash Type Injury Surfing?? Or What? She is getting ready to have MRI without contrast. Sheila Carney
