Why would a person get blurry eyes and wiggle linethat are not clear but in fact are black? i have other symptoms such as cheek get burn, fingers numb

Possible migraine : Your symptoms sound consistent with a migrainous event. The squiggly lines in your vision, the tingling facial sensation, & the numbness in your hand are not infrequently associated with migraines. If this is a new event for you, an eye MD would be helpful to make certain your eyes are okay, and perhaps a neurologist to secure a diagnosis & treatment plan for you. Good luck.
