Tension-type headache (TTH) is the most prevalent type of primary headache. Unlike migraine, however, there have been no significant treatment advances for chronic TTH in the past few decades, probably due to the limited understanding of its pathophysiology compared with that of migraine. The objective of the present study is to investigate the cerebral function imaging changes in patients with chronic tension headache trough comparing that in healthy people, focus on the regional homogeneity (ReHo) of ROIs of brain. In addition, the effect of acupuncture and Fu's subcutaneous needing (FSN) on the cerebral function will also be studied. This is a clinical trial study, randomized, in parallel, single-blinded assessor, and with a sham placebo control.
