Folliculitis following greater occipital nerve block.

Among headache syndromes cervicogenic headache is a common problem which originates from region of the neck. When wide range of pharmacological treatment options are inadequate, interventional procedures are applied.[1] After trigger point injections, greater occipital nerve block (GONB) which is the most frequently applied technique among interventional methods has an important role in the treatment of cervicogenic headaches.[2] Although the possibility of complication after GONB is very low, some side effects e.g. bleeding, infection, and allergic reactions can be seen after the application. [3] Folliculitis is a skin condition which occurs with inflammation of the hair follicles.[4] No report was obtained about association of GONB and folliculitis after an extensive database search. We report a case of folliculitis as a rare complication of GONB.
