I've been having headaches span all across my head for maybe the last week or so. Sometimes my ears hurt and there's some numbness, other times my left or right hurts, depending on where I can feel the headache. I get some tingling in my fingers and toes but not too much, as I experienced those long before the headaches started. Recently I've been getting eye twitches. I've had migraines in the past but the doctor stated it was due to dehydration. What is going on with me?
