About seven years ago I had a hypertensive crisis with numbers similar to
@pdgoldinc It was accompanied by an unbearable ice-pick headache - absolutely the worst pain I have endured so far. The doctor had no idea what was wrong but he did prescribe a combo BP medication. He "treated" the headache with a CT scan which showed nothing. I got nothing for the pain.
Since I had recently started Cymbalta I asked if it could cause my symptoms. He insisted it could not, but fortunately I did not believe him so I immediately reduced the dose, and that stopped the headache. When I checked the manufacturer's professional information sheet for Cymbalta, extreme hypertension was listed as a "rare" adverse effect.
My BP is always high at any doctor's office. I used to think it was just the "white coat syndrome", but now I think it's a combination of "white coat syndrome" plus hyperadrenergic POTS, which is made much worse by having to sit up in the exam room for a long time while waiting for the doctor.
Like other folks have mentioned, my pulse and BP tend to be all over the place. I have found a low-dose beta blocker (I use atenolol) to be very helpful in controlling the tachycardia and hyperadrenergic symptoms like feeling hot and having cold and clammy hands and feet at the same time.
I have found that POTS is a more "acceptable" illness to present with. More doctors seem to understand that POTS is "real" and treatable. The psychobabblers have not been as successful in convincing doctors that POTS is a "psychosomatic" illness perpetuated by "false illness beliefs".
