The headache profile section included items on headache duration, frequency, location, quality, intensity, aura, and characteristics of accompanying symptoms (nausea, vomiting, photophobia and phonophobia), and the impact of physical activity on headache.
The trend toward a structural similarity in the chronification of TTH and migraine may resemble the clinical scenario, in which chronic migraine often loses its vegetative characteristics (accompanying photophobia, phonophobia, nausea, vomiting, and headache exacerbation with physical exercise) and thus resembles TTH [59].
Various maternal characteristics were associated with nausea and its treatment.
Bilateral, constant, dull ache of mild to moderate intensity without preexisting aura, vomiting, nausea is characteristic of TTH.
Five patient characteristics were positively associated with postchemotherapy nausea (females, history of motion sickness, drowsiness and prechemotherapy nausea) and two with postchemotherapy vomiting (ECOG performance status of 1 and 2 and consumption of 10 or less alcoholic drinks per week).
With some distance the "Physical quality of life" (characteristic 4) with less diarrhea or nausea, as well as the "Possibility to participate in social life" (characteristic 6) followed on the same level.
