Nobody figured out the cause of the hypertension. They called it "intractable hypertension" and said about 5% of population has this type that they can't pin down the cause.
So you went to see some doctors and they couldn't figure it out but you went to another doctor and he did but doctors are useless?
That's kind of how medicine works.
The medication combo was figured out by current doctor, but that's because I kept record of all the meds I tried and so he simply noticed that I didn't try any beta blockers. Nothing amazeballs. If anything, that doctor I saw after hospital stay was a totally useless chump. He has 4 months to find me something. Got me down to 170/110. Useless.
