I got the Shingrix vaccine this morning and experienced nothing but a sore arm today, until I went to bed and started chilling - can't stop shaking, even my very warm husband holding me doesn't make me feel warm, normally I would have had a hundred hot flashes. Fingers and toes old, body warm to touch but not feverish. Tylenol OK? better idea? Truly miserable, so tired but can't relax
