I am a 47 year old female, family history of heart attack. I have been on bp meds for 5 years. I have not been feeling well for a few months. My BP fluctuates - it is better after taking my bp med Lysoprine. Last night I had a spell and my legs were shaky, clammy, sweaty, and nauseous. then I yawned uncontrollably for 10-15 minutes. My neck became sore and stiff. The feeling passed, but a Blood pressure check a couple of hours later revealed 180/109. I checked it 3 times. I had been lying in bed - so no reason for BP to be elevated. I've also had a headache for 3 days - but that went away when i had the spell. These spells are not unusual. My doctor thinks it's stress - but I've removed a major stessor in my life. I've never had any tests ran other than blood tests. Once my doctor mentioned chromophecytoma or something like that, but he said i would be sweating more - dripping with sweat. I'm worried and don't know at what point i would go to the ER.
