Hi Jen,
My balance problem has always been from my E and not migraines. Also it's not good to use a mobile phone because the frequency is very high and especially if the phones antenna is close to your head you are picking up a magnetic field which can effect the brains tissue and cause more problems. Both my epi and neurosurgeon told me to stay away from mobile phones because of how it can lead to more sz. and damage the tissue in the brain. Here's wishing you well and May God Bless You!
