In the morning when I woke up the first week approximately of March I got out of bed and the room began to spin. My whole body seemed like it was on a weird trajectory - couldn't walk straight due to vertigo/dizziness. It passed. I was able to function throughout the day. It happened every day of that week and every night when I got home from work I would be exhausted and have a terrible headache and have blurred vision. March 3rd - I got home late from work and didn't feel good and just felt sick. I took my own blood pressure: it was 180/120. Fortunately, my partner had Clonidine - and that brought it down to 130/70. I felt like I was safe to stay home and I called my doctor's office that night and left voice mail. The soonest I could go in was March 5th. She (the doctor) seemed to dismiss my suggestions that it was bigger than a blood pressure issue. She listened to my heart and lungs and took my blood pressure: 150/100. She suggested that I needed to start taking blood pressure meds and that I needed to exercise more etc and that I was a little overweight. I am very active and I watch my diet - she basically dismissed my suggestions. She prescribed Losartan: she recommended to take it and come back in three weeks. I took it for three weeks and during that time I had  symptoms that manifested: pain and inflammation in my neck and it radiated along my left side of my jaw and as high as left ear. Throbbing and burning pain there. Around that third week, looking in mirror, I noticed an obvious swelling on my left throat and bottom of my thyroid. Headaches, trembling, fatigue, hot flashes - I was having. The weirdest syndrome was: burning mouth syndrome. I felt like I had burnt my tongue on hot coffee - it would get worse as the day went on (the burnt tongue feeling). I went back to the doctor on March 26th. To make complaint about all the new symptoms that were happening -  including my voice being horse and breaking. She felt my thyroid and she said there was definitely something going on. March 29, Ultrasound done. I have an Endocrinologist now - she did another Ultrasound and Biopsy. She did a referral to surgeon: she is oncologist (for Thyroid) - a specialist for Thyroid. Note: on May 20 - Rashes and bumps on my skin -I had started having those symptoms when I was on Losartan. I saw a nurse practitioner about my skin and she put me on different blood pressure medicine on the 20th to Hydrochlorothiazide - and I'm still taking that today. Saw a Dr on May 26th and she did another ultrasound right then. I have other nodules on the right side of my thyroid but they are very small. She decided to do a Lobectomy - to take the left lobe only at first so a natural thyroid hormone still being made. July 8th - had the left lobe of Thyroid removed. The next day, all of my immediate pain from the cyst and a huge amount of inflammation was gone. It was amazing. I have had a follow up with surgeon on 16th of July. I have seen my endocrinologist yesterday. I have a final surgical  follow up on the 27th along with blood work in between to evaluate everything. My endocrinologist says there is a direct connection between COVID infection and thyroid - even people who don't have a serious case of COVID. I did not have a serious case of it. The inflammation caused by the vaccines may have contributed to  the seriousness of the cyst and the size of it.
