Appreciate your response. My reaction does not seem to be a common occurence, with a rapid system response within a 3 hour time frame, following insertion of the Mirena.
I only have one other factor to consider as a possile cause. I did take 2 Tylenol No.3, before the procedure and 1 Tylenol No. 3, following the procedure. It sounds like a more likely probability that the symptons were due to an adverse reaction to Tylenol No.3.
