I'm 24, female, 123 lbs on average, and exercise less than I used to. I'm posing here because I have been to my doctor and am waiting on a visit to a neurologist, but I think it might be heart/circulatory related. I'm a full time student and spend a lot of time sitting down to study.
For the past three-four years I've been having attacks where the back of my head tingles, then I get so dizzy that I can't stand. In the more severe attacks the dizziness comes from my vision flipping around, and in the mild ones my vision doesn't flip but still sort of moves? I can focus on what I'm looking directly at, but my peripheral looks a little like a cartoon. The attacks happen when I'm doing anything; standing, sleeping, sitting, etc. It has literally pulled me out of REM. The very first one was when I was moving a medium weight box. I'm posting this here because: I feel like it happens more frequently when I've been sitting cross legged more often. When I make an effort to sit with a totally straight back and not cross my legs at all, the frequency of these attacks lessens; however, they do not go away completely. Maybe heart related?
Leaning forward for more than a few minutes (ex: sitting on the floor wrapping gifts) will make me mildly dizzy/nauseous until I lay flat on my back for a while. I'm usually sitting with crossed legs in this position. Laying on my belly and propping myself up onto my elbows to read causes a similar effect after a while.
The other symptoms are listed because I think they -might- be related/helpful. Hopefully this post won't feel too messy.
Over the past year, my heart has been skipping beats every now and again. That area goes numb for a few seconds at a time when this happens. Thankfully, this happens maybe once every six months. Once in September, my heart beat so fast that I couldn't stand up and I actually called an ambulance. By the time they arrived, my BP was down to 120. They released me after a quick ER check.
For the past five months, I've been having intermittent stabbing pain on the right side of my chest. Sometimes it'll be stabbing several times a day and other times I will have no pain for a week. An x-ray was taken one month ago and nothing was found.
In July, I was working outside in the heat for hours a day. We were moving a bunch of boxes/bending/stooping a lot. I didn't have a dizzy attack or any heart issues that I noticed; however, my legs have started twitching a lot. They never used to. When it began, they would twitch in one or two places ~18 hours out of a full day. Now they only act up every few weeks, but it just goes on and on for a few days. I post this because I've read that it could have to do with the tissues not getting enough O2, and it may be related to the dizziness/legs being crossed? I notice it a lot more right after I lay down.
On a similar note, I've had occasional random stabbing pain all throughout my body for maybe 10+ years. I've asked around and the only other person that gets this is my sister.
Please let me know if I should provide more details. I've listed everything I can think of right now. I feel like it could be heart, circulatory, neurological, or spinal? I'm no where near being a doctor though.
Thank you in advance for any suggestions/ideas!
