Re-heating chicken in microwave?

I got a hot chicken roll in the shop this morning but by the time i got home about 2 hours later it had gone cold, so i put it in the microwave for 1 minute then ate it. Im just wondering if its ok to do that with southern fried chicken? I felt a bit sick after eating it probably because i thought it might make me sick, but now i feel fine. I wont get food poisoning or anything will i?
