I typed out a very long post detailing everything that's happened and decided I don't like it. I'm going to try to make one more to the point and more about my conclusions to try to summarize a very long series of events.
I'm wondering if it's possible for my body to hide the symptom of low blood pressure? Mainly as a result of something like an anaphylactoid reaction. There was an incident in the past where my body managed to keep my blood pressure completely stable when it shouldn't have been able to. I had a horrible stomach virus that caused severe vomiting and the inability to process even water for 48hours. I was severely dehydrated but when they tested my blood pressure between laying down, sitting, and standing it remained nearly the same. My heart rate however shot up and they basically said if it wasn't for that and how healthy my body was I would have been passing out everytime I stood up.
I've been having basically attacks lately where my heart rate and breathing spike. The first real attack seems to have been caused by a CT scan to try to find out why I was having random mild episodes of heavy breathing and my resting heart rate was in the 90s when it's normally in the 60s. I had repeated increasingly worse spikes in heart rate and breathing immediately following the CT scan and then more mild ones for the next 12 hours. My blood pressure and oxygen level remained good. Many many tests were done. They determined my heart and lungs were functioning fine and none of the blood tests came back odd except an elevated d dimer that noone can account for. That was about a week ago. I've been doing increasingly better the past week except getting out of breath and tired easier than normal and easier than anyone my age and physical level should.
That changed tonight. The previous episode lasted 12hours before it really dropped off and it took days to have my heart rate come back down to where it was before that. Tonight after a week of nothing it spiked again. This was much quicker and sharper. It started with my breathing increasing while I was laying down and my heart rate followed. For about 30mins it spiked and dropped repeatedly with the drops lasting longer and longer until I felt normal again. I got very very cold until it went away. Within hours I feel exactly as I did before except tired cause it's now 3:30 and I took my sleeping pills late so I can't sleep yet.
My husband mentioned it looked like anaphylactic shock. I wasn't exposed to any allergy though which led me to thinking anaphylactoid instead. The only thing I did immediately prior to the episode was breathe in some of the flour and spice mix for gingerbread cookies we were making and then drink lemonade to get rid of the spicy taste. The symptoms seem to match better than anything I've looked up over the past week or the doctors have tested for and low blood pressure matches the tiredness and most of the mild symptoms I had prior to this except for the fact through the entire first episode at the ER and a 24hr hospital stay after that my blood pressure tested normal. I don't remember the exact numbers but it was considered pretty much ideal by the doctors even when they attempted to stress my body further. So can my higher heart rate and the fact that in all tests done so far my body seems very efficient at correcting itself manage to counter low blood pressure? My body just seems constantly stressed but noone can find a cause. At first I thought maybe my brain was just sending out weird signals but that doesn't really match how my body has worked in the past. My brain does have some issues like insomnia but physically I've always been able to withstand a lot and anytime there's been a problem it's always turned out to have a physical reason. Even down to the things I dislike to eat which I turned out to be lactose intollerant and sensitive to those things I avoid. I think my body is trying to counter something noone can see. Perhaps because it's doing such a good job of it. Like I said it's proven to be efficient at correcting itself and withstanding stress.
