I had my 2nd Shingles vaccine 1/13/23. I had pain at the injection site and achy leg muscles shortly thereafter. Had a slight headache that night that faded. But most surprising was the intensive headache I developed on day 3 along with the night sweats that started on day 2. Yes. My night-shirt was wet enough each time I had to change in the middle of the night. I never had this reaction before to a vaccine. Was quite concerned my hormone regulating system had been affected. My headache was also different in that it mostly hurt on the sides of my head, (not the front), and it hurt in the back of my head along the outer left and right edges from just above the base of skull down to my shoulder blades. Also I noticed sound sensitivity. It’s now 1/18 and the symptoms have subsided. I’m just thankful it did not turn into a long sustained systemic effect. And I’m hoping I never need to get another shingles vaccine.
