Changes in mechanical sensitivity following CFA injection into trapezius muscle. HWT measured in facial skin for 15 days after CFA or saline injection into the ipsilateral trapezius muscle. The inset indicates the stimulus site. *p < 0.05 compared with saline-injected rats. Data represent mean ± SEM. (n = 10 in each group; two-way ANOVA with repeated measures, followed by Bonferroni’s multiple-comparison tests).
