If you've been advised by your PT to stop exercising, listen to your PT. You don't want to make matters worse! If you find you're still hungry, make sure you're including enough healthy fats in your diet, which is key for keeping me satisfied for much longer. I'll include ground flax, avocado, nuts, nut butters, etc. in my meals, along with a protein source, and I'm good for hours. I made pancakes for breakfast at 9:30 using egg whites, oats, a banana and ground flax, and I'm still not hungry for lunch!
