The first time I got an initial attack was about May 2, 2021. I felt a flushing sensation, my heart was racing, nauseous, dizzy, and my blood pressure was high at the time, but I didn't know it. I had to lay down.  I felt terrible for several hours. I just laid in bed, I didn't know what was going on. Then I felt better the next day. I had a couple of these events off and on with same symptoms. I didn't check my blood pressure so at the time I didn't now it was high. May 10th I saw my doctor. I was also having pain in my gut. She did bloodwork and said to go to gastroenterologist. She increased the dosage of my blood pressure medication. I seen the  gastroenterologist and she performed an upper GI and a colonoscopy but didn't find anything. June 9th I went back to my doctor because I was continuing to have the same attacks. My blood pressure was 170/110. I have never had anything like this before previously before having the COVID vaccine. I got a really bad attack at work on June 17th. I work with senior citizens and help take care of them. I felt fine in the morning and then by 1:00pm when I was going to bathroom I was dizzy, vision was swimming, and I thought I was going to pass out. I looked at my heart rate and it was 130 BPM. I still didn't know that my blood pressure was high at that time. I laid down, and I didn't feel good at all. I tried to rest and stay calm. At that point I had to call my company and send someone to come in for me so they could release me. I felt my heart rate racing  and fluttering. I went to urgent care and my blood pressure was 190/ 117. They kept me there for about 3 or 4 hours. By then my blood pressure came down, and my symptoms kind of subsided. They wanted me to go over to the hospital, but I didn't want to. So did they did an EKG that showed my heart rate and blood work was okay. They released me, and then I went home. June 22nd I called my doctor. Before April 12 the last time I saw my doctor was December 2020 but since getting the vaccine I have been to the doctor so many times and taking so many different test. June 29th I talked to my doctor about my symptoms and she increased my blood pressure medication again. July 8th I had to leave work again. This time it was late at night. I had gotten a blood pressure monitor and it was getting high even while taking my blood pressure medication that was adjusted to a higher dosage. I went into ER again and they kept me overnight because of heart racing and blood pressure was so high. I asked them to check my adrenal glands. And I found out that I have an issue with my adrenal glands. They diagnosed me with hyperaldosteronism. My endocrinologist said that that diagnosis shouldn't cause the symptoms that I have been having except for my potassium being low and having a racing heart.  The doctors still don't know why I am still having these attacks if my potassium isn't low. I had to go to ER again in October 2021 because of an attack I had in September 28th at work. I had the same symptoms. My blood pressure was 180/110. My doctor boosted blood pressure medication again to an even higher dosage. I started a new medication for hyperaldosteronism which is spironolactone 50mg, 2xday.  September 29 I got another attack and went to the emergency room. Since then I have still had some attacks. I have missed 10 working days from all of this over the course after getting vaccine. I have a couple more appointments coming up. Symptom causes are still unknown. I am going to see a more experienced endocrinologist next month. I have almost passed out twice. I have felt horrible ever since getting the vaccine. I really didn't want to get the vaccine, but due to my previous health and my job I decided to take it. July 8th i was hospitalized. I have been to my doctor 6 times since April 2021. I usually see her every 3 or 4 months.  Now I am in and out of the hospital.
