welcome to the forum. its possible that your african grey was stressed by your absence. As marie83 pointed out above, a return to basic training and watching the birds body language to avoid bites is absolutely vital. After a while, i think your grey wil come back to normal, but it may take a LONG while, and you need to be patient.
I am having a similar problem with my GCC who was a perfectly sweet bird his whole life. But he got spooked by roadwork noise six months ago and became an almost vicious biter, attacking both my and my husband. But he is definitely getting better, as I have been working with him for six months clicker training him. it takes a long time for the bird to regain its confidence after an emotional upheaval. but you need to have faith in the bird and don't give up on him. the main thing, in my opinion, is avoiding the bites because once it becomes habitual, it is very hard to undo. but even then it can be done.
this may require some training through the cage bars with the target stick, etc. check out these training methods as they are detailed elsewhere on this forum and blog.
Good luck with your bird!!
