I have had 4 ablations and was able to go back to work 3 days after each of the procedures.The last one was in March 09. I never had any chills or headaches. I did have a very dull ache in my chest but that went away after a day or so. The entry site in my groin ached a bit longer but it was definitely not a pain that I could not stand. I just walked a bit slower for a couple of days. If your husband has a fever and is not feeling well, call the doctor.

I had ablation about a month ago and had no side effects, I was fine in 24 hours. Have you called the dr for advise? I would call dr since he is running a fever. He should be feeling fine by now. Good Luck!
