I Just Passed Kidney Stones For The First Time. They

I just passed kidney stones for the first time. They put me on oxycodone for the pain. I stopped taking them about two days ago and my tentacles are still sore I'm just now starting to use the restroom which hurts due to my poop being hard. I had to take a enima to go. My stomach feels like its empty but I'm really naucious and I can't get my appetite back at al . What do I need to do. For my stomach and my testacles hurting?
