As amish asked in his reply, do you suffer with anxiety issues? Have you been dx'd with an anxiety disorder?
We need more information to even attempt to give you a reasonable response.
How long has this been going on? Do you have any other symptoms with this? What do these pains feel like and exactly where are they located? Do you have a history of migraines or other headaches?
Even if and when you send up more information, our response is going to be that you should see your doctor as soon as possible. Sudden onset of head pains and dizziness is not something you should ignore. I don't want to scare you, but you really need to see your doctor.
Please let us know what they say.
Peace
