I also had muscle weakness, nausea, confusion, a delay in my speech, and
hot flashes that traveled up and down my body. I called my old primary and they told me to wait off the side effects of the imitrex instead of going to the ER. My head continued to burn for two months when another doctor finally pulled me off of the serotonin medication. The burning is gone for the most part but I am left with what they are now calling generalized dystonia.
