Throbbing headache for entire week, never left once, sometimes feels like it's burning inside my scalp, no family history of headache, never had one before, prevents me from sleeping, sometimes get these tremors where my head/jaw shake for a few min?

You should be examined by your doctor, especially if it is keeping you awake and you are having tremors. It still could be from a virus, or stress, or a migraine...but you need a full exam to make sure it's nothing more serious. If you have persistent vomiting, or other weakness, blurry vision, or other new symptoms, and your doctor is not available, please seek care at the ER.
