Toothpain symptoms and conditions

I have been on this med (25 mg) for eight days to treat SSRI resistant depression. Three days ago I developed flu like symptoms, with fever and vomiting. While I have hypertension I have also seen an increase in my BP even though I am taking my BP medications. However the most difficult to deal with side effect is extreme tooth pain that started when the flu symptoms did. It is so painful I have to eat soft foods. I have had no dental problems in over 25 years. Has anyone else had this effect?
