The picture shows that analgesic effect of EA could be detected immediately (30 min) after treatment.

(Control: saline injection; CFA: CFA injection; ipsilateral: EA treatment on the same side of CFA-induced inflammation; contralateral: EA treatment on the contralateral side of inflammation. *p < 0.05 as compared with control group, #p < 0.05 as compared with CFA group, n = 8.
