You can run a fever because of emotional distress. Central nervous system arousal is heating. his is why we use expressions like "hot for someone" (sexual attraction ) or "hot under the collar" (anger prone). Early in PTSD one of the symptoms loved ones noticed is that I suddenly became very warm. Later I developed fevers that could not be medically explained.

Conversely, because fever may accompany trauma, fever may trigger traumatic symptoms. So if you warmed up under traumatic conditions you migbt take a chill and experience fever as very threatening or
threatening or saddening without knowing why.

Medical questions are best addressed to your doctor. My best guess is she will not diagnose you with PTSD. You are always welcome to come here and discuss PTSD anyway.
