Yeah, my GRE is about 7 years old, so if it is required I will need to retake. I am only looking at Duke, UVA, and Northwestern in the T14, I am assuming it will be a rarer requirement outside of that.
You might want to explore accommodations if your GI medical condition substantially limits your life activities. If so, you may qualify for being allowed to stop the clock to excuse yourself to go to the restroom.
So, you wouldn't be interested in pursuing a legal career if it doesn't entail going to a top school? Thats what I'm getting from the 169 comment. The answer to that question is probably relevant to your goals and interests.
