The day of booster I was fine, the next day I had a sore arm, fever, chills, body aches, headache, all of the flu symptoms besides vomiting. I had the same symptoms with all of the Pfizer vaccinations the following day. The day of booster I was fine, the next day I had all of the flu symptoms and remained home from work. On Feb 15 I went to see my PCP, and was put on anxiety medication (fluoxetine 10mg) I was on that for 2 weeks until my PCP asked I move up to 20MG. On 3/2/22 I had a runny nose & cough. On 3/3/22 I stayed home from work sick, and was throwing up, I also remained home on 3/4, 3/5, and 3/6. 3/7 - 3/11. I was managing with mild headaches that regular over the counter tylenol was helping. On 3/14 I was getting more of a tension headache. On 3/15, I had the same headache but worse than any I had before it was making me throw up. I called my doctor on 3/16 and she recommended I go to the ER as I was also hearing a swishing in my ear. I went to local hospital and there they did a CT Scan. On the CT scan with contras they saw some carotid arteries in my neck, and transferred me to ICU for Treatment & Monitoring since being in the hospital my Blood Pressure was extremely high. I stayed at ICU and did some more testing where they found out my carotid arteries on both sides were Torn also. I have had NO trauma to my neck which would cause these dissections, and we do not have connective tissue disease in my family. I am able to leave ICU on 3/18/22 and they sent me home with some headache medication. I was home on 3/19 & 3/20 by continuously taking blood pressure/blood thinner medication also, and could not take what I was previously. On 3/21 the headaches started again and 3/22 was my follow up with PCP, when I left her office she said my BP was still really high and she didn't like that I couldn't get the headache under control. 3/22 she sends me back to the ER and I go to alternate Hospital, they ran some more testing and they called ICU who said I was released from their care and there was nothing more they could do. Alternate Hospital releases me with Norco, which isn't solving the issue, as I have dissections in my neck and they are also torn/clotted. on 3/23 I am following and taking the Norco every 4-6 hours to help my headaches and they are not subsiding, so I end up going to another hospital, and they re-run all new scans and find a 3rd dissection in the Vertebral artery. I stayed at hospital for 2 days after a bunch of tests were ran, they released me with blood thinners, 2 blood pressure meds, sleeping night meds, and headache medication. I was unable to get answers from most of the doctors as to how this came about as it was very random and nothing that I could think would set this off besides the C-19 Booster. They let me know the medication that I thought was causing this was not and that my BP was so high because of these dissections that was the cause for my headaches. After speaking with all of my doctors it had nothing to do with prior medications and since I have stopped taking those and am only on BP, Blood thinners, headache meds, and not sleeping meds, I still have a lingering headache and it hurts to turn my neck from side to side.
