achilles tendon rupture repair

I have a question that appears to be the opposite of J. Giles.
I had surgery for a ruptured tendon, and the operating surgeon moved.
I am at 10 weeks recovery now, and the new doctor has suggested that I can do light jogging, squats, and basically anything I want.
My foot is still swollen, which he says is normal.
I have not even been given any exercises for physical therapy yet.
Should I go back to running so quickly, or is it much too soon? Are there exercises I need to do first?
I play rugby and want to get back to the game, but I am very wary of reinjury–I can’t go through the surgery again! Any advice would be greatly appreciated!
