I am a 23 yr old female, i have been suffering froofromm high bp from paapastst 6 7 months(no reason at all, all tests including CP, TSH, T4,  Fasting,  Cholesterol, vitamin D,  ECG,  EEG) i am perfectly fine according to them. But i am having these heart palpitation for which i am taking a beta blocker advised by doctor and for bp a helpful drug as well,  i still in some parts if the day (usually from evening to night time) have severe headache kind of feeling which only effects my temporal region (both sides) and i then have blurry vision,  pain in my neck and my mouth goes dry and jaws hurt like anything. I have no idea what is causing all this,  but its really painful.

 I am still an undergraduate i need to focus more on my degree and lesser on these painful distractions which make me feel like a 60 yr old grandma. I would appreciate any help i could get.
