Lightheaded/dizzy with a headache off and on for 3 days strait what is most common reasons. ?

Tension headache: This part of the application is very confusing to me! There is really not enough information to answer here. Could be migraine, vestibular neuronitis,, viral illness, "hangover", herpes simplex or zoster involving auditory nerve, anxiety. BTW, check your spelling and grammar on the question. Ouch!

Headache/dizzy: There can be MANY causes. Best to have this checked out by a healthcare provider. Best of luck
