This study tests if low-level laser therapy (LLLT) with different light wavelengths can help people with cervicogenic headache, a type of headache caused by neck problems. Adults aged 18-65 with this headache for at least 3 months will try one of three LLLT treatments (675nm, 820nm, or a mix of wavelengths) along with regular physical therapy like stretching and exercises. The study will check pain levels, how often headaches happen, neck movement, disability, and quality of life over 6 weeks, with follow-ups at 3 and 6 months. the investigators want to find the best LLLT option to reduce headache symptoms safely.
