I got both the flu shot and the pneumoshot the day after finishing Omnicef for a sinus infection, and I got the worst cold!!!
I am now just getting over it after a week. It could have been other things too, the weather here in WI has been loopy, 60's then 30's then 60's then 30' again with in two weeks.
I thought I'd be smart and asked for the flu shot in the left
arm, because I mostly lift things at work with my right. The nurse forgot I was supposed to get both, and then gave me the pneumo shot in the right arm. That's the one that hurt for a week!
Hope you screwed up in reverse and all went weel for you, sunnydaze1 !
