The investigators conducted a multicenter, prospective, randomized controlled clinical study to learn whether fire needling combined with filiform needling applied to pericranial muscle tenderness areas can effectively treat chronic migraine with comorbid tension-type headache. The study will also evaluate the safety and long-term efficacy of this therapy. Its main target questions include:
1. Can fire needling significantly reduce the number of headache days per month?
2. What is the effect of this therapy on headache intensity, emotional symptoms, and quality of life? The investigators will compare "fire needling at pericranial tender points plus conventional filiform needling" versus "conventional filiform needling alone" to verify whether the key technique of fire needling plus conventional filiform needling provides unique additive value.
Participants will:
1. Receive treatment twice per week for 8 weeks (either in the experimental group or the control group)，attend a follow-up visit at week 24 after enrollment
2. Keep a headache diary (recording headache frequency, pain intensity, duration, associated symptoms, etc.)
3. Regularly complete assessments of emotional status, quality of life, and number of pericranial tender points
