My Mother Is 79 And The Last Couple Days Is

my mother is 79 and the last couple days is having severe spasms on the left side of her head - it is very hard for her to describe this as she is deaf but it hurts her very much. We were at the hospital today and they did a cat scan and ekg and she apparently is normal. we have been home a couple hours and she is now in more pain than ever. I don't know what to do
