4‐AA reduces capsaicin‐induced pain‐related behaviour following PGE2 pretreatment. (a, b) 4‐AA reduces capsaicin‐induced pain‐related behavioural responses following pretreatment with PGE2. *P< .05, significantly different from (PGE2+capsaicin), #P< .05, significantly different from (PGE2+capsaicin+4‐AA); one‐way ANOVA with Tukey's test
