Several: Multiple sclerosis can impair neurological functions; depending on what lesions you have or may acquire, it could affect your vision and your motor skills so that driving, for example, could be dangerous. You should talk this over with your neurologist to establish what you should or should not do. Also, the medications you may be prescribed may have some risks, especially infection.
