I’ve Had A Headache For Two Weeks. It’s Generalized And

I’ve had a headache for two weeks. It’s generalized and low grade but hard to get rid of with Advil. I’ve also started the past five days having my equilibrium out of whack, almost like Ifeel high. I went to the Internist and told him I’d had an inner ear virus that lasted for a year from a flu vaccination, so he thought it was something with the inner ear or allergy related. He said to try Claritin which I did today. It helped with the foggiest but not the headaches. I’ve lived in Southern California for 7 years and never had this problem with allergies. What do you think?
