I broke my ankle , had surgery , then fell on it?

i broke my ankle then had surgery and everything is going well and im in the walking boot right now and i kinda tripped on my ankle and fell, should i be worried? everything is healed back right? i have a plate and 14 screws. after falling my ankle feels even more loose and easier to walk? did i screw up anything or prolong this hassle of a broken ankle?i dont think i could rebreak it so easy. i dont feel any pain, just a little in my heal... My foot is now sore. should i be worried or whats the next step i start PT next week. thanks for your help!
