What Causes Pulsating In Lips,forehead And Left Side Of Face?

My father has had a neurological workup, heart has been checked, taken Botox, had EMG, taken muscle relaxers, taken Lyrica, and numerous other meds. He also had lower back sx (back feels great) in the last six months. He developed STAPH and took six weeks of antibiotics via pump. He had a hernia repair within six months. He also had an esophageal repair (not sure exactly what) within eight months. For the last six months he has been having a pulse feeling in his lip, forehead, and left side of face. It is not all the time but when it lasts he will develop a tension headache. He has started smacking his lips and pulling at his face when it gets intense. He will rest more than usual. He is not one to take any medicine other than ibuprofen or Aleve. He does have high blood pressure which is under control on medicine and an irregular heart rhythm, also under control for years on medicine. He describes it as feeling his heart beat in his lips and forehead. He will sit and count the beat.
