Migraine that can’t be fully kicked.

Went for a root canal two weeks ago. The day after I started experiencing facial pressure and headaches. Developed into a never ending migraine with facial pressure. Ended up in ER for a cocktail that brought some reliever but didn’t kick it fully. Then got on steroids (having terrible side effects from those). Still have a lingering in and out headache and facial pressure. This sucks. Primary care visit on Wednesday.
