1st branch- V1 (ophthalmic branch)goes to the scalp, forehead and the region around the eye
2nd branch- V2 (maxillary branch) goes to the cheek area
3rd branch- V3 (mandibular branch) goes to the jaw area
TN more commonly affects the 2nd and 3rdbranches causing pain over the jaw and the cheek area. The patient generally experiences a severe, sudden, sharp, stabbing, burning or shock-like sensation lasting for a short duration with frequent episodes throughout the day.
