Does anyone know anything about gall bladder surgrey?

I have been having gall bladder attacks i have had 7 in 2 and a half months.I recently went to the emergency room and they told me I had multiple gallstones and i needed to have it removed.Well since my visit last week i have never stopped having pain my abdomen is very tender and i cant lift or even walk with out pain.Plus I have a slight fever.Could this be sign of infection.I am planning on going in for the surgrey.Has anyone had this surgrey and do you know what happens during it,what recoup time is or just any information good or bad on this I would really appreciate it.Thank you so much
