爸爸有高血压，但一直吃最少剂量的降压药，维持的都挺好。可是最近1，2个月突然血压上升，带他看了家庭医生，增加了剂量，是以前的3倍还开了新药，但血压到晚上还是有上升，一般是170/90. 尤其是半夜，头疼。很担心。想问问这的姐妹有没有什么类似的经历。会是什么原因。如果看专科，看什么科，要做些什么检查。英文叫什么？谢谢。

Usually family practice will handle adjustment of blood pressure meds.  Blood pressure medicine is tricky to adjust, and needs time to work out.  My grandmother had similar situation, but now is much better with increased dosage.  Go back to the family practice doctor and emphasize the headache accompanied by the high BP.  If he has a sudden drastic increase in pain, or systolic blood pressure beyond 180's, take him to the ER.
