Standing Up

Not sure what is going on but every time I stand up after sitting for any length of time I get a raging headache with intense pressure in my head/ears. I agree ... it sounds like blood pressure. But my blood pressure is coming down to more reasonable levels. I guess I should bring the cuff with me to work for a few days so I can check it during the day and especially at the times that I get the headache. But that's usually when I have been sitting for a while and need to go to the bathroom NOW! (Wouldn't I look cute racing down the hall with a blood pressure cuff hanging off my left arm?) What's really weird is that when I get to the bathroom and sit down the pressure dissipates immediately. The headache isn't so considerate. It generally hangs on for a while. I suppose it's more of the same "adjusting to new meds" thing. Hope it ends soon though. I don't like it!
