Fainting spells or passing out

I have never had this problem before but yesterday before work I was making my kids breakfast and felt everything go dizzy. My head was lightheaded, tingling in my hands and feet and then I woke up on the floor with my boyfriend over me calling my name. It happened two more times by 10 am so my boyfriend ended up calling 911. When the paramedics got to me they took my blood pressure and it was slightly elevated but when they had me stand and took it again I passed out and my blood pressure went down. I kept going in and out (twice due to the sitting me up and laying me down) on the way to the hospital and even once at the hospital. I got X-ray, labs, CT scan, urinalysis, and EKG. They couldn’t give me any reason for the multiple fainting spells throughout the day. I just got an IV and told I was “young and healthy” and to follow up with my PCP. They said it was vasovagal syncope.

Now today I passed out in the hallway and my boyfriend was above me again trying to wake me up. I don’t know why this is happening but I hate it. My palms get sweaty and I feel lightheaded and shortness of breath and my heart feels like it’s trying to jump out of my chest when it happens. I have the worst headache from the dizzy feeling. I’m worried and without answers I’m trying to deal with this at home.

Im not pregnant and I drink water all day for other reasons and haven’t changed my diet or anything. Heart problems do run in my family but my EKG was fine and my heart rate was in the normal range. Only thing weird was my blood pressure going up and down.

I do have an appointment set up for next week but anyone else deal with something similar?
