Additional information: I am a colleague so as part of training I just wanted to self-report that I received the Covid booster shot yesterday evening. All the side effects I am having started today and have also been reported as possible side effects of the vaccine, although I did not have any side effects with the first two shots. I began experiencing a very sore arm around noon. About two hours later, I had fatigue, muscle aches, headache, slight nausea, and slightly elevated temperature of 99.4. My baseline is usually 97.5ish so it was enough of an elevation to make me aware I had slight fever. It is back down to 98.5 now but I'm still tired and have a migraine. Note, I also get pretty severe migraines and have had them since I was 5 years old, so I can't tell if it's from the shot or now. In any case, I know I need to report everything. I also take prescription Ibuprofen 600 mg as needed for migraines. I did not take that the day before the shot, but I did use it a few times that week. I also use a once per month migraine preventative injection-Almovig. However, I did not take that the two weeks leading up to my booster. I also take Sumatriptan for migraines as needed (up to 9 per month). Other than that, I take supplements including vitamin, B, C, D, Zinc, Probiotics, Elderberry, Collagen supplements, Magnesium, Butterbur, and hair skin and nail vitamins. Have had headaches almost my entire life. This has been managed by doctor since I was a child. My BMI is elevated, over 30 and hence why I got the booster shot. It puts me in a higher risk category. Patient not diagnosed with covid-19 prior to vaccination and since vaccination patient not tested for covid-19. The patient had no known allergies. Patient was not received any other vaccine four weeks prior vaccination. No initiation of new medication/ other treatment/ procedure. This case assessed as non-serious by the reporter.  Follow-up attempts are completed. No further information is expected.
