Its always a bit elevated in a medical setting, but depending on why im in that setting can send it soaring. I spent 9 days in hospital, split over 2 separate admission/discharge and the longer I was there and the more IVs i blew (eight was the final tally, nearly one a day) the higher my BP would go. I got pissed because pain & nausea werent being adequately controlled BUT they wanted to drug me for BP.
Anxiety elevates my BP and exercise, specifically walking, is how i deal with the anxiety. Theoretically I had patio privileges, meaning i could leave my room, go outside and walk the trails on property go anywhere inside the hospital at any time, BUT, its 110 degrees here in the desert during the day and night staff insisted i stay on IV fluids and O2 monitor even though I was off narcotics and drinking & eating normally. Third night I just took off my O2 monitor, grabbed the IV pole (who id named Chris) and headed outside. Magically, it brought down my BP, but I still had to fight to exercise (no pun intended) my privilege.
Its so frustrating to know your own body, but get so much resistance from medical staff to care for your body! I keep a BP log at home to keep me off BP meds.
