I Have Been Out Of Duloxetine For 4 Days. I

I have been out of Duloxetine for 4 days. I believe I am having some health issues because of it. Stiff neck, some vision clarity, headache (have been taking 2 extra strength Excedrin) daily (usually before bed) I have an appointment with my lady doctor on the 31th of May, so will be without the Duloxetine until I get a new prescription from her. Could all my "head" problems be caused because of this? I wondered why I am so weepy and emotional.
